1Do app addresses

These app addresses are identical on Sepolia and Base Sepolia. Deployment manifests also include test tokens, NFT drops, and test borrowers; they are not core protocol dependencies.

Integration requirements

Do not scatter hardcoded addresses through feature code; read deployments or a unified ENV_CONFIG.
In browsers, prefer the connected provider for eth_call and eth_getCode to avoid chain mismatch.
Verify that the address's ERC-7702 delegation target is the expected AccountImplementation.
Addresses and status may change with testnet releases; re-check 1do-core deployments before launch.

Testnet only

The addresses listed here are not mainnet production deployments. Do not send economically valuable assets to them.
