USDC exists on Ethereum, Solana, Polygon, Base, Avalanche and a dozen other networks. They are different networks with different rules. On EVM networks your address can look the same on each of them, and on a network like Solana it is a different address altogether — but either way a transfer arrives only on the network it was sent on, and one sent on the wrong network does not bounce back.
This is why Receive in Smartable does not show "your address". It lists each asset on each network, with a filter to narrow the list. You pick the pair; the app shows the address and QR code for exactly that pair.
What to send the other person
Three things, together:
- the network name, spelled as the sending app spells it;
- the address for that network;
- the asset.
"USDC on Base" plus the address is unambiguous. "My USDC address" is not. When you share from Receive, the message Smartable writes names the asset and the network for you.
A plain QR code carries only your address, not the asset — the sender's wallet decides what to send. Payment request can add an amount and a note, but check what the sender's app actually shows before you rely on it.
If they send from an exchange
Exchanges name networks their own way — the same network may appear as ERC‑20, Ethereum, or ETH mainnet. Match the network, not the label, and ask for a small test amount first when the amount matters.
Sending to an exchange: memos and tags
Some networks use an extra field to tell an exchange which account a deposit belongs to — a destination tag on XRP Ledger, a memo on Stellar, a comment on TON. When you send to an exchange that asks for one, copy it from the exchange's deposit screen into the matching field in Smartable. The field is offered when you send the network's own coin. Without it, the deposit can arrive and not be credited to you. Sending to a person does not need one.
What the app shows
- “This code carries your address, not USDC — the sender chooses the asset.”
- “Exchanges use this to credit a deposit to your account. Leaving it out is how deposits go missing.”
Security note
Never share your recovery phrase, private key, password or device PIN. Smartable will never ask for them or ask you to sign a transaction to “verify” or “recover” your wallet.
