Fixed yield. Backed by stake.
ETH bonds whose contracts rely on the Ethereum protocol alone, with no oracles and no governance.
For holders
Buy a bond with ETH and receive an NFT that pays a fixed amount on a set date, backed by one validator’s stake. Start with the holder guide.
For developers
The contracts’ published source, the deployed addresses and the system contracts they build on. Start with Networks and addresses.
Coffer runs on the Hoodi test network. Test ETH has no value.
