Ethereum-compatible wallets
Self-custodial wallets that work on Ethereum mainnet, and by extension on the network SAIHM settles stablecoin payments over. SAIHM does not require a wallet — the free tier and every card plan work without one. This list is here for the minority who would rather settle in stablecoin or hold their own signing hardware.
Each entry is verified against the project’s primary-source URL. The list is not exhaustive and not editorial endorsement.

Do you need a wallet at all?
Most people do not. The free tier needs no wallet and no card — you run one command and approve a one-time GitHub sign-in, or start from /free in a browser and sign in with Google or Microsoft. Paid plans are billed by card through Stripe worldwide, and by card or M-PESA through Paystack across Africa. A wallet is only needed if you would rather settle in stablecoin, or you want the signing key on your own hardware.

If you do use a wallet
SAIHM derives your identity key from any Ethereum-compatible wallet using HKDF. There is no SAIHM-specific client SDK and no proprietary key format, so every wallet in the tables above works and none of them locks you in. Upgrading does not change your identity: whichever key you started with keeps opening your memory when you move from free to paid. Swapping in different key material, on the other hand, starts a new and empty memory — so if you began on the free tier, keep booting from the key file it created rather than replacing it with a wallet-derived secret.
Stablecoin settlement is in USDC.e at no premium over the card price, paid directly or gasless via a signed authorization. Other Ethereum stablecoins (USDT, DAI, PYUSD) must be bridged or swapped to USDC.e first. See the stablecoin section of /pricing for the rate table.
