Supported Chains
Pi Protocol is currently deployed on Ethereum, which serves as the base chain for all smart contract activity, token issuance, vault logic, governance, and compliance enforcement.
Ethereum was chosen for its maturity, security, and wide acceptance across DeFi ecosystems. All protocol contracts—governing the minting of USP and USI, collateral management, staking, treasury operations, and access controls—are live and fully operational on Ethereum mainnet.
Key components on Ethereum include:
-
USP: Issued as an ERC-20 token with ERC-4626 extensions. This makes USP compatible with DeFi protocols like Aave, Compound, and Curve. It supports transfers, vault interactions, staking into the LAMP, and integration into lending and liquidity systems.
-
USI: Minted as an ERC-1155 NFT. Each token represents a unique yield-bearing position tied to a specific RWA deposit and vault. Metadata dynamically updates to reflect yield accrual and maturity.
-
USPi: The governance token of Pi Protocol, used to participate in protocol decisions, staking, and fee-sharing. USPi holders govern whitelist/blacklist entries, protocol upgrades, treasury allocation, and new vault approvals.
-
Whitelist/Blacklist Compliance: All token contracts enforce dynamic whitelisting and blacklisting logic. Only approved addresses can mint or transfer USP and USI, ensuring institutional-grade compliance. These rules are enforced through lightweight mappings and governed by on-chain proposals.
-
Vault Contracts: Smart contract-based vaults manage RWA deposits, collateral locking, yield calculation, and redemption. Each vault is linked to a specific asset class (e.g. T-Bills, IIAs) and includes logic for haircut application, maturity tracking, and position accounting.
-
Treasury and LAMP: The Liquidity and Minting Pool (LAMP) and treasury mechanisms operate on Ethereum, supporting USP peg stability, mint-to-earn incentives, and protocol reward distribution. Fee flows, yield redistribution, and reserve allocations are all executed on-chain.
All protocol actions—whether minting, redemption, staking, or governance—occur transparently on Ethereum. This provides users with verifiable security and minimizes reliance on off-chain infrastructure.
Pi Protocol’s architecture is fully compatible with Ethereum tooling, including wallet providers, custodians, institutional integrations, and DAO management systems.
