Question 3

Fees on ChainPort

Accepted Answer

How are Porting Fees Calculated?

Porting fees are 0.3% or 0.2% of the port value at the time of porting tokens depending on the payment method. If you wish to pay for the transaction in the form of the ported token or chain tokens, fees are 0.3% of the value of the transaction.

Pay for the Porting Fee

Pay for the porting fee using PORTX tokens. The PORTX tokens will be deducted automatically from the staking contract. You can learn more about PORTX in:

Fee distribution

ChainPort’s fee mechanism ensures long-term sustainability for a cross-chain bridge. The mechanism essentially turns ChainPort and PORTX tokens into an ecosystem with incentives for holders and crypto projects. By turning ChainPort into a fully-fledged ecosystem, it will become the defacto bridge of choice for whoever wants to port tokens.

Fees on Ethereum

ChainPort charges extra gas on the source chain to cover the minting and sending of the tokens on the target chain. On most chains, this cost is small and usually doesn't pass ~$1.5, but when bridging to Ethereum the gas cost becomes more significant and changes frequently due to gas demand and cost on Ethereum.

Question 5

The Token’s Contract Address Changed After Bridging

Accepted Answer

Why Did I Receive a Different Token?

If you've received tokens with a different contract address after bridging with ChainPort, don't worry – it's part of the process. When bridging tokens via the lock and mint bridging method with ChainPort, you get a ChainPort-wrapped token on the target chain with a different contract address. A token’s contract address changes depending on the blockchain it operates. You can double-check a token’s contract address on different chains on CoinGecko or blockchain scanners.

Why is There a Difference:

A wrapped crypto token is typically a digital asset converted to function on a blockchain network other than its original one. This ensures cross-chain compatibility and easy exchangeability.

Check Liquidity:

To ensure liquidity, always check the contract address of the token you're trying to port. Visit our explorer to verify if the project has officially chosen ChainPort as its bridge.
