All EVM-compatible chains work out of the box. AgentaOS uses a pluggable chain architecture — if it speaks EVM, it signs.

​
How It Works

Agenta doesn’t care which chain you target. The signing protocol operates on raw transaction hashes. The chain adapter handles serialization, gas estimation, and broadcasting. Pick a network when you create a signer: 
agenta init --name my-agent --network base
Or specify it per transaction: 
agenta send 0xRecipient 0.01 --network arbitrum

​
Testnets

Start with testnets. Every mainnet chain has a testnet counterpart.
Use Base Sepolia for development. Fastest block times. Free faucet ETH from Alchemy.

Roadmap

Bitcoin

Native Bitcoin adapter. Taproot signing via the same 2-of-3 threshold protocol. Planned.

Solana

Ed25519 threshold signing for Solana transactions. Planned.
