Assets for financial applications
Metal assets can represent stablecoins, tokenized deposits, fund interests, securities, commodities, and internal settlement units. MIP20 records transparent balances, while MIP410 represents privately held value in a shared shielded pool. MIP20 tokens can also pay transaction fees, so users do not need a separate native gas currency. Learn about assets on MetalProgrammable payment controls
Metal provides payment-control primitives that institutions can compose into policies for their own products and operating requirements. A MIP20 transfer evaluates attached policies within the transaction that moves the token. A refused transfer either reverts or places the funds in quarantine for authorized recovery. MIP410 checks private policy proofs separately at payment initiation and resolution. Learn about programmable compliancePrivate payments
Ordinary token transfers on a shared network reveal the asset, amount, sender, and recipient onchain. That visibility can expose customer relationships, treasury activity, and payment volumes that payment providers, financial institutions, and their business customers need to keep confidential. Metal supports shielded payments that hide those details from public observers while preserving policy enforcement. Learn about private paymentsEthereum compatibility
Metal preserves the EVM development model, including Solidity contracts, 20-byte addresses, standard transaction types, and JSON-RPC. Its main differences concern asset-based gas, zero native value, payment controls, and deterministic finality. Learn what changes for Ethereum developersInteroperability
Metal is designed to use proofs of finalized state when coordinating activity across chains. This allows relayers to deliver information without giving them authority over the payment or its outcome. Learn about Metal interoperabilityPayments by agents
Agents pay for APIs over x402 in*USDZ, from a key of their own or from an
account whose owner set spending limits on chain. A hosted facilitator submits
the transfer and pays the gas, and any payment can be checked on chain.
