Exfer provides a permissionless proof-of-work blockchain and a CLI-first toolset for autonomous machine-to-machine commerce. It implements a UTXO model, a deterministic scripting language (Exfer Script) for covenants (HTLCs, multisig, vaults, escrow, delegation), and a JSON-RPC interface so agents can create wallets, send payments, and automate trust-minimized workflows.
Use Exfer when you need programmatic, on-chain settlement between agents or services: atomic swaps and HTLCs for escrowed payments, multisig for joint custody, timelocks for recoverable vaults, or simple wallet automation integrated into agent workflows. Ideal for experiments or integrations that require predictable costs and composable transaction scripts.
Works with agent tooling that can call command-line CLIs or HTTP JSON-RPC endpoints (general-purpose automation agents, CI runners, and bots).
