USDC is an issued dollar-oriented stablecoin with canonical, native, and bridged variants across networks. Contract events and issuer controls differ from a network-native gas asset. The source is a stablecoin contract or recorded native representation, while LINK is classified as token. Check the quoted output rather than assuming a one-dollar source unit fixes the destination amount.
Chainlink is classified as a governance or utility token for this route. LINK uses a network-specific contract asset on Base. The Base side is contract-tracked rather than a native gas balance. LINK arrives as a network-specific contract balance. The wallet still needs the destination native asset before it can transfer or approve LINK later.
Polygon is a L1 EVM network in the Polygon ecosystem. POL pays source-side network gas on Polygon. EVM 0x account address A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1.
Polygon source execution occurs on L1, while Base delivery occurs on a separate L2 ledger that settles to ethereum. POL pays source gas and ETH is the destination gas asset; identical-looking wallet addresses do not merge the balances or transaction histories.
USDC is classified as a stablecoin for this route. USDC uses a network-specific contract asset on Polygon. The recorded Polygon representation uses 6 decimal places. 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.
Base is a L2 EVM network in the Ethereum ecosystem. ETH pays destination-side network gas on Base. EVM 0x account address A Base receipt belongs to the Base L2 balance and token contract, not Ethereum L1; later activity needs ETH specifically on Base.
Route-specific mistakes include sending on a network other than Polygon; using a destination that is not valid for Base; running out of POL before the source transaction is submitted; selecting a stablecoin by ticker without checking its network contract. 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. A Base receipt belongs to the Base L2 balance and token contract, not Ethereum L1; later activity needs ETH specifically on Base. LINK arrives as a network-specific contract balance. The wallet still needs the destination native asset before it can transfer or approve LINK later.
Polygon wallet, token-transfer, contract, log, and gas activity remain public, and Base wallet, token-transfer, contract, log, and gas activity remain public. For this USDC on Polygon to LINK on Base path, Private Route is intended to reduce the direct visible relationship between activity around the source-side EVM 0x account address and destination-side EVM 0x account address; it does not hide either chain's public records.
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.
LINK is a contract representation on Base at 0x88fb150bdc53a65fe94dea0c9ba0a6daf8c6e196. ETH, not LINK, 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. LINK arrives as a network-specific contract balance. The wallet still needs the destination native asset before it can transfer or approve LINK later.
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, LINK arrives as a network-specific contract balance. The wallet still needs the destination native asset before it can transfer or approve LINK later.
USDC is the deposited stablecoin input; LINK is the quoted token output. Source allowance or native-spend rules and destination wallet/representation checks are evaluated separately.
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. LINK arrives as a network-specific contract balance. The wallet still needs the destination native asset before it can transfer or approve LINK later.
USDC must match its Polygon representation. A ticker or target price is not enough to identify a token contract.
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.
Requirements are checked for the live USDC Polygon to LINK 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.
