ARC is purpose-built for programmable money. USDC is the native gas token — you pay transaction fees in USDC, not in a separate ETH-like asset. This eliminates the dual-token gas problem common on other chains.
Amount-only binding
ARC is EVM-compatible. Like Base and Tempo, ERC-20 transfers carry no memo field, so AlgoVoi binds checkouts by amount uniqueness. Send the exactamount_microunits from the checkout response and do not round.
USDC decimals — important
On-chain ARC USDC uses 18 decimal places (unlike 6 dp on every other chain). AlgoVoi’s verifier handles this scaling automatically — amounts in the API and checkout response are always in the standard 6 dp micro-unit format. You never need to scale yourself.Wallets
Any EVM wallet works, configured for ARC Testnet:- AlgoVoi Chrome extension (in-house wallet, native x402 / MPP / AP2 on ARC via viem
signTransaction+ native value transfer — Arc’s native gas token is USDC; six-chain coverage as of v2.6.0) - MetaMask — add network manually (chain ID

ERC-8004 onchain agent identity
ARC defines ERC-8004, a standard for registering AI agents as onchain identities with reputation and credential verification. AlgoVoi is registered on ARC Testnet as an ERC-8004 agent:| Agent ID (ERC-721 token) | 5938 |

ERC-8183 job settlement (Tier 3)
ARC also defines ERC-8183 for USDC-escrow job settlement between agents. AlgoVoi plans to support ERC-8183 job settlement in a future release, enabling agent-to-agent payment flows with onchain escrow and conditional release.Agentic protocols
ARC Testnet is fully supported by AlgoVoi’s protocol stack:See also
