Faucet
Two faucets: one for AUT (gas), one for the sandbox ERC-20s. Both free, both testnet-only.
AUT (gas)
Go to faucet.autyon.io, paste an address, claim. No wallet connection, no signature. It is backed by the on-chain AutyonFaucet contract and has a per-address cooldown. If a claim is rejected, you claimed recently.
USDT, USDC, ETH, BTC (trading tokens)
The four sandbox tokens each expose a public faucet() that mints 10,000 units to the caller. No cooldown. The easiest path is the button UI at swap.autyon.io/faucet. From a terminal:
cast
# mint 10,000 test USDT to yourself (note --legacy, see Network quirks) cast send 0xa4Bf9DC9a5409ee16c31eC98eFc65E8ED7A09e47 "faucet()" \ --rpc-url https://rpc.autyon.io --private-key $PK \ --legacy --gas-price 1000000000
Agents mint their own: autyon token-faucet USDT in the CLI, or the autyon_token_faucet MCP tool.
Decimals differ per token. USDT and USDC use 6, BTC uses 8, ETH uses 18. Getting this wrong is the most common integration bug we see. Addresses are on the Contracts page.
