What Is Metal Blockchain?
this kind of blockchain is a Layer 0 open-source platform developed by Metallicus Inc., designed to power high-throughput, compliant financial applications. It builds on the Snow consensus protocols pioneered by Avalanche, adding a fourth subchain called the A-Chain (XPR Network) optimized for payments and decentralized finance. The platform supports multiple virtual machines, so developers can write smart contracts in Solidity, C++, or TypeScript. By incorporating ISO 20022 messaging and BSA compliance at the protocol level, metal targets banks, credit unions, and fintechs that need a secure, scalable entry into Web3.
Layer 0 Architecture and Avalanche Consensus
A Layer 0 blockchain is the foundational settlement layer for an entire network of independent subchains. blockchain adopts the Snow Proof-of-Stake mechanism, where validator nodes reach finality in under two seconds. This consensus model avoids energy-intensive mining and achieves finality probabilistically, making it suitable for real-time settlement. The protocol is forkable: new subnets can define their own validator sets and virtual machines while inheriting the security of the primary network.
Subnets and Scalability
this type of blockchain’s subnet architecture lets institutions launch private or public blockchains that are fully interoperable. Each subnet can achieve 4,500 transactions per second (TPS), and because subnets run in parallel, the theoretical total throughput is unlimited. This design contrasts sharply with monolithic chains where every application competes for the same blockspace. A bank could operate a private subnet for interbank settlements while connecting to public subnets for customer-facing DeFi services, all without compromising compliance.
Metal Blockchain Tokenomics
The native asset, METAL, is the unit of account for transaction fees, staking rewards, and governance. With a hard-capped supply of 666,666,666 METAL, the token carries deflationary properties through fee burning. This model aligns incentives for validators, developers, and users while providing a predictable monetary policy, which is a key requirement for institutional adoption.
METAL Token Supply and Distribution
The initial distribution broke down as follows: 142,333,333 METAL to the Metal Foundation for development and grants; 71,000,000 METAL to founders, subject to a 12-month vesting schedule; 120,000,000 METAL for community conversion from the legacy MTL token; and 333,333,333 METAL for staking rewards, released gradually to secure the network. As of mid-2026, the circulating supply sits at approximately 507 million METAL, according to data from Kraken and CoinGecko.
MTL Token Conversion History
Before this kind of blockchain launched its own chain, Metallicus operated the MTL token on Ethereum as the native asset of the Metal Pay ecosystem. When metal went live, existing MTL holders were given a conversion path: 120,000,000 METAL was reserved specifically for this migration. The conversion was designed to be non-dilutive to new METAL holders, since the migrated supply came from a pre-allocated pool rather than new minting. This transition effectively moved a payments-focused community from a single-chain ERC-20 model to a full Layer 0 network with subnet capabilities.
Fee Burning and Deflationary Mechanism
Every transaction on blockchain incurs a fee paid in METAL. Those fees are permanently burned, reducing the total supply over time. The C-Chain employs a dynamic base fee that rises when network utilization exceeds a target threshold, further curbing spam. This mechanism mirrors Ethereum’s EIP-1559 but operates across all subnets. As network adoption grows, the burn rate could eventually outpace staking emissions, creating sustained supply compression.
Key Compliance Features for Financial Institutions
this type of blockchain’s embedded regulatory compliance stack is what separates it from general-purpose Layer 0 networks. The protocol integrates W3C digital identity standards, Bank Secrecy Act (BSA) requirements, and Swift’s ISO 20022 messaging format, enabling direct integration with existing banking infrastructure without custom middleware.
FedNow Integration and Real-Time Payments
Metallicus became a FedNow Service-certified provider, meaning its infrastructure connects directly to the Federal Reserve’s instant payment rail. This certification allows credit unions and community banks using this kind of blockchain to offer real-time digital asset settlement alongside traditional fiat rails. The Temenos partnership further validates enterprise readiness, as documented in a joint solution profile on Temenos.
WebAuthn and Self-Custody Security
To reduce the friction of private-key management, metal is implementing Web Authentication (WebAuthn) support for EVM accounts. Users will sign transactions using biometric sensors (fingerprint, Face ID) built into their browsers or mobile devices. A planned on-chain key recovery protocol will allow institutions to reset user keys through administrator-controlled permissions without ever accessing confidential data, bridging DeFi self-custody with enterprise security requirements.
Pros and Cons
Pros
- Compliance-first design: BSA, ISO 20022, and FedNow integration are built into the protocol, not bolted on afterward.
- High throughput: 4,500 TPS per subnet with unlimited parallel subnets gives institutions room to scale without competing for blockspace.
- Multi-VM flexibility: Solidity on the C-Chain and C++/TypeScript on the A-Chain means most enterprise development teams can work in familiar languages.
- Deflationary tokenomics: Fee burning with a hard-capped supply of 666,666,666 METAL creates predictable monetary policy.
- FedNow-certified: Direct connection to the Federal Reserve’s instant payment rail is a rare credential in the blockchain space.
Cons
- Limited exchange listings: As of mid-2026, METAL is not on Coinbase or Binance. Over 99% of daily volume flows through Metal X, concentrating liquidity risk.
- Early adoption stage: FedNow pilots are still in testing with credit unions; broad institutional deployment has not yet materialized at scale.
- Price well below ATH: METAL trades around $0.13, roughly 92% below its all-time high of $1.65, reflecting speculative uncertainty.
- WebAuth Wallet still in development: The most compelling UX feature for mainstream banking customers is not yet fully live.

Always verify the contract address: 0x294559fa758c88d639fd085751e463fee7806eab.
Metal Blockchain vs. Other Layer 0 Protocols
Metal Blockchain competes in a Layer 0 space where Avalanche and Polkadot have significant head starts in developer mindshare. The table below compares the features that matter most to developers and enterprise users.
| Feature | Metal Blockchain | Avalanche | Polkadot |
|---|---|---|---|
| Consensus | Snowman (PoS), sub-second finality | Snowman (PoS), sub-second finality | Nominated PoS (GRANDPA), ~12s finality |
| Maximum Subnets/Parachains | Unlimited, 4,500 TPS each | Unlimited, 4,500 TPS each | ~100 parachains, ~1,000 TPS each |
| Smart Contract Languages | Solidity (EVM), C++, TypeScript (AVM) | Solidity (EVM) | ink! (Rust) |
| Regulatory Compliance | BSA, ISO 20022, FedNow-ready | No built-in features | No built-in features |
| Native Token Supply | 666.6M METAL, hard cap | 720M AVAX, capped | 1.4B DOT, inflationary (approx. 10% annual) |
| Key Recovery | Planned on-chain, biometric reset | None (wallet-level only) | None (wallet-level only) |
Why Compliance Matters
Avalanche and Polkadot are general-purpose platforms that leave compliance entirely to the application layer. Metal Blockchain’s built-in digital identity and ISO 20022 support means banks don’t need to build custom compliance middleware on top of a generic chain. That reduces integration timelines from months to weeks for institutions already running Swift-compatible systems.
Performance Benchmarks
Both Metal Blockchain and Avalanche deliver sub-second finality using the Snowman consensus engine. Metal Blockchain’s addition of the A-Chain and its WASM-based execution environment offloads payment-related transactions to a more resource-efficient subchain, which can lower fees for high-volume micropayments compared to routing everything through the C-Chain.
Developer Tools and Multi-VM Flexibility
Metal Blockchain inherits Avalanche’s multi-virtual-machine architecture, letting developers deploy Solidity-based dApps on the C-Chain (EVM) while simultaneously using the faster A-Chain (AVM) for payment-oriented logic. This dual-VM approach gives teams flexibility without sacrificing tooling compatibility.
Solidity on the C-Chain
The C-Chain is fully EVM-compatible, meaning developers can port existing Ethereum smart contracts with minimal changes. Tools like Hardhat, Remix, and Truffle work out of the box. Gas fees are paid in METAL, and the address format is identical to Ethereum’s 0x-style. Here’s a minimal Solidity deployment targeting the Metal Blockchain C-Chain:

}
}
}
Deploy this with Hardhat by pointing your hardhat.config.js RPC URL to the Metal Blockchain C-Chain endpoint. No other changes are required from a standard Ethereum deployment workflow.
C++ and TypeScript on the A-Chain
The A-Chain uses the Antelope (formerly EOSIO) protocol with WebAssembly (WASM). Smart contracts can be written in C++ and TypeScript, languages familiar to many enterprise development teams. WASM execution runs at near-native speed, making it well-suited for high-frequency trading or real-time settlement logic where EVM gas overhead would be prohibitive.
Roadmap and Institutional Adoption
With Metallicus driving development and the Temenos partnership providing enterprise distribution, Metal Blockchain is actively onboarding credit unions and community banks. The upcoming PulseVM upgrade aims to further optimize block production and validator performance, as announced on the project’s official X account in June 2026.
PulseVM: What the Upgrade Targets
PulseVM is the next execution environment upgrade for Metal Blockchain, focused on reducing validator latency and improving block propagation across subnets. While full technical specifications haven’t been published as of mid-2026, the stated goals include tighter integration between the C-Chain and A-Chain for cross-subnet atomic swaps, and improved throughput for the FedNow settlement use case. Developers building on the network should monitor the official X account for testnet release dates.
FedNow Explorer and B2B Integration
Through the FedNow Explorer program, several credit unions are testing Metal Blockchain for instant settlement of member payments. This real-world pilot shows how a Layer 0 blockchain can coexist with central bank infrastructure. According to CoinGecko analysts, this type of central bank rail integration is expected to accelerate across the industry through 2026 and 2027.
WebAuth Wallet and On-Chain Key Recovery
The most anticipated user-facing upgrade is the WebAuth Wallet, which eliminates seed phrases by using FIDO2 biometrics. Combined with the planned on-chain key recovery protocol, Metal Blockchain could solve one of crypto’s most persistent usability problems: lost private keys. That makes it far more palatable for mainstream banking customers who have no tolerance for irreversible key loss.
“The combination of FIDO2 biometric authentication and on-chain key recovery represents a meaningful step toward making self-custody viable for retail banking customers,” according to analysis published by CoinGecko in their 2026 institutional blockchain coverage.
Frequently Asked Questions
Is Metal Blockchain backed by physical metals?
No. The name “Metal” refers to the strength and resilience of the network; there is no gold or silver peg. The token derives its value from network utility and fee burning, not any commodity backing.
Can you buy Metallicus on Coinbase?
As of mid-2026, METAL is not listed on Coinbase. The primary markets are Metal X, MEXC, and the Metal Pay app. Check the official Metallicus website for any future exchange listings.
What is the METAL token used for?
METAL pays transaction fees (which are permanently burned), secures the network through staking rewards, and will eventually carry governance rights. It also serves as the unit of account across all subnets on the network.
How is Metal Blockchain different from XRP?
XRP is a payment settlement system designed primarily for currency exchange between financial institutions. Metal Blockchain is a full Layer 0 platform that hosts multiple independent subnets, each with its own virtual machine and rule set. Metal Blockchain also embeds BSA and ISO 20022 compliance at the protocol level, whereas XRP relies on external integrations for regulatory adherence.
Where can I store METAL tokens safely?
METAL can be stored in any Ethereum-compatible wallet like MetaMask or Trust Wallet by adding the contract address manually: 0x294559fa758c88d639fd085751e463fee7806eab. The upcoming WebAuth Wallet will offer biometric-protected storage without seed phrases, which is the recommended option for institutional users once it launches.
What is the maximum supply of Metal Blockchain?
The maximum supply is hard-capped at 666,666,666 METAL. No additional tokens can ever be minted. A portion of the supply is allocated to staking rewards, released gradually according to the network’s emission schedule, while transaction fees are burned to offset emissions over time.
