What exactly leaves Polygon as USDC?
USDC is a contract representation on Polygon with 6 decimals at 0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359. POL, not USDC, pays gas unless both symbols are the same. A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. The source wallet sends the exact USDC native or contract representation selected by the route; contract USDC can require approval and the chain’s native gas asset.
What exactly arrives on Base as SOL?
SOL is a contract representation on Base with 9 decimals at 0x311935Cd80B76769bF2ecC9D8Ab7635b2139cf82. ETH, not SOL, pays gas unless both symbols are the same. A Base receipt belongs to the Base L2 balance and token contract, not Ethereum L1; later activity needs ETH specifically on Base. Native SOL receipt uses a Solana address and can fund later fees; wrapped SOL uses an SPL token account and tokenized SOL elsewhere is not native.
Why does the USDC to SOL direction matter?
The source wallet sends the exact USDC native or contract representation selected by the route; contract USDC can require approval and the chain’s native gas asset. On receipt, Native SOL receipt uses a Solana address and can fund later fees; wrapped SOL uses an SPL token account and tokenized SOL elsewhere is not native.
What changes between the source and destination asset roles?
USDC is the deposited stablecoin input; SOL is the quoted native-asset output. Source allowance or native-spend rules and destination wallet/representation checks are evaluated separately.
What should be matched before sending USDC?
The source wallet sends the exact USDC native or contract representation selected by the route; contract USDC can require approval and the chain’s native gas asset. A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. A Base receipt belongs to the Base L2 balance and token contract, not Ethereum L1; later activity needs ETH specifically on Base. Native SOL receipt uses a Solana address and can fund later fees; wrapped SOL uses an SPL token account and tokenized SOL elsewhere is not native.
Which stablecoin contract must this route match?
USDC must match its Polygon representation. A ticker or target price is not enough to identify a token contract.
What funds the Polygon source transaction?
POL is the native gas asset for Polygon. A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. USDC is token-tracked and can need approval before transfer.
Can I swap USDC on Polygon to SOL on Base without KYC?
Requirements are checked for the live USDC Polygon to SOL Base quote. Verification requirements can depend on the provider, amount, jurisdiction, and current route. Sasquatch does not verify this route as universally no-KYC; check the live flow before continuing.
