Swap POL from Polygon to AVAX on Avalanche C-Chain

Swap POL from Polygon to AVAX on Avalanche C-Chain. Native POL leaves Polygon. Native AVAX is what can arrive on the C-Chain. Both quotes use the gas label, and they are different coins. The destination is not the X-Chain.

0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE means POL on chain id 137 and AVAX on chain id 43114. There is no ERC-20 on either side. Polygonscan shows the POL debit. Snowtrace shows the AVAX credit. Blocks near 2 seconds on either chain are not the bridge. How to bridge assets between chains explains the shared label.

Diagram for Swap POL from Polygon to AVAX on Avalanche C-Chain
POL leaves Polygon. AVAX is what can arrive on Avalanche C-Chain.

POL and C-Chain AVAX share only the label

Spending the label reduces POL. Receiving it increases AVAX on the C-Chain. WAVAX at 0xB31f66AA3C1e785363F0875A1B74E27b85FD66c7 is not the credit. If you needed the wrapper, switch quotes.

The last POL cannot start the C-Chain

You are spending the fee coin. The last POL cannot pay chain id 137. Wrapped POL at 0x0d500B1d8E8eF31E21C99d1Db9A6444d3ADf1270 is the wrong balance. This route never approves that contract.

The AVAX can pay the C-Chain

That is the point of the native label on chain id 43114. It is not a stablecoin. POL against AVAX can move. Take the minimum or refresh. No finish time is published.

X-Chain explorers stay empty for this pair

X-Chain AVAX will not appear. Snowtrace is the C-Chain explorer. If a wallet is pointed at the X-Chain, you are looking in the wrong place.

Frequently asked questions

What is the best way to swap POL from Polygon to AVAX on Avalanche C-Chain?

0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE means POL on chain id 137 and AVAX on chain id 43114. There is no ERC-20 on either side.

Why do both addresses match?

Because 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE marks native gas on each EVM chain. On Polygon, chain id 137, it is POL. On Avalanche C-Chain, chain id 43114, it is AVAX. You do not approve it. Polygonscan shows the debit and Snowtrace shows the credit. They are not one balance. The X-Chain is a different system.

Is this a way to mint WAVAX?

No. WAVAX is 0xB31f66AA3C1e785363F0875A1B74E27b85FD66c7. This route pays native AVAX. If a contract needs the wrapper, wrap after the AVAX arrives, which spends a little of that AVAX. Snowtrace should show a native balance first, on the C-Chain only. Do not look on the X-Chain. WAVAX is a later wrap, not this quote.

What if I hold wrapped POL?

Stop. The wrapped contract is 0x0d500B1d8E8eF31E21C99d1Db9A6444d3ADf1270. This page spends native POL only, and it also needs native POL for the fee. Unwrap, then leave a remainder. Snowtrace will not show AVAX from a wrapped-only wallet. Unwrap to native POL first, and do not spend the last unit on the fee.
