The Base payTo is an interim Coinbase-custodial address, controlled by the operator. The Solana payTo is a separate operator-controlled address; payments credit its USDC token account. Neither is a Safe or multisig. A non-custodial upgrade is planned for Base. These two are the only settlement addresses for API calls.
Old host and wallet: do not use
horizon-pulse.vercel.app and the old Safe 0xe16A1b12404cB2EbC6e783beCA6E2A9253c3dC7E are no longer used. Don't send payments there.
