How Do You Use Portal Bridge to Transfer Tokens?

Portal Bridge moves supported tokens between chains using Wormhole’s cross-chain messages. For a Solana-to-Ethereum transfer, use Portal Bridge to move the supported token to a recipient address on Ethereum. A Wormhole Portal Bridge transfer finishes when the destination transaction credits the expected token, which may be a wrapped version. What Is Portal Bridge, and What Token Arrives? Portal Bridge is a token bridge app for moving supported assets between Solana, Ethereum, and other supported chains. The key question before sending is what representation of the token will arrive: the original asset or a version issued through a bridge. Wormhole’s Wrapped Token Transfers (WTT), called Token Bridge in its contracts, lock an original token on its home chain and mint a Wormhole-wrapped token on the destination chain. On the return trip, the wrapped token is burned and the original is released. No token travels between blockchains; the contracts change which chain holds the spendable b...

Can a Large Polygon Bridge Deposit Hit a Token Cap?

There is no single token cap for every large Polygon Bridge deposit. A cap is a rule that limits how much of a particular token can move, and the limit may apply to one transfer, a time period, or the bridge’s total available backing. A cap may come from the bridge, the token contract, or the route handling the transfer. Splitting a deposit helps only when the per-transfer cap is the binding limit. Check the token, direction, cap window, and remaining allowance before sending a large amount. A token cap limits a specific amount or window A token cap is a programmed ceiling, not a general rule that all bridges share. A contract may reject one deposit above a per-transaction maximum, count deposits against a daily or rolling limit, or apply both rules; a rolling window measures recent activity continuously instead of resetting at midnight. For example, imagine a bridge with a hypothetical 24,000 USDC per-transfer limit and a 40,000 USDC rolling 24-hour limit. A 50,000 USDC transfer would...

Inspecting Token Balance Changes After Rebases

Image
A rebase can change a token balance without a transfer. For a treasury team, the task is to separate that supply adjustment from payouts, deposits, and price movements before reconciling the books. Rebases change balances through token rules A rebase changes a token’s supply according to its contract, and holders’ balances may shift proportionally even when their wallets make no transaction. Positive rebase: balances typically rise as supply expands. Negative rebase: balances typically fall as supply contracts. Transfer: tokens move between addresses and are recorded as a transaction. Excluded balance: some contracts exempt particular addresses, such as liquidity pools, from the adjustment. Many rebasing tokens track each holder’s “shares” and apply a changing index to calculate the displayed balance. In simplified terms, if a treasury holds 10,000 units and a negative rebase reduces balances by 1.5%, its expected balance becomes 9,850. A later 500-unit payout would leave 9,350; t...

How to Check a Chainflip Boost Falls Back

A Boosted Bitcoin deposit can save about 20 minutes, but only when Boost liquidity is available. If it isn’t, the deposit waits for the usual confirmations, so you can judge the speed benefit without assuming it is guaranteed. Boost liquidity decides whether the deposit gets a head start Boost is an option that lets a swap begin before the source deposit has completed its usual confirmation wait. For Bitcoin, the normal wait is about three blocks, or roughly 30 minutes; a Boosted deposit may proceed after one block. That early start depends on Boost liquidity: funds that liquidity providers set aside to cover deposits while they are still waiting for full confirmation. The protocol checks whether enough is available for the whole deposit. Boosting is all or nothing, so a shortfall means the entire deposit follows the regular confirmation path. After a Bitcoin deposit appears in a block, validators check it and the available Boost funds. If enough is available, the protocol uses those f...

3 Checks Before Retrying a Failed Token Swap

Image
Before retrying a failed token swap, check whether the transaction is pending, confirmed as failed, or already succeeded. These three checks tell you whether to wait, investigate a revert, or verify your token balance. That distinction matters because resubmitting while the first transaction is still pending can create confusion or replace it. Start with the transaction hash, not the app message Find the transaction hash in your wallet’s activity and look it up on an Ethereum block explorer. A swap page can lose connection or time out after broadcasting; that does not prove the network rejected the transaction. For a Fermi swap, as with any wallet-based exchange, the hash is the durable reference for checking what happened on-chain. If there is no hash, the transaction may never have been broadcast, or the wallet may not have completed signing. Check the wallet’s pending activity too: a transaction can be submitted before its hash appears in the service’s own activity view. If neither...

AVAX or WAVAX: What a wallet swap needs on Avalanche

Image
A swap on Avalanche C-Chain needs native AVAX for its network fee; WAVAX can be the token you trade, but it cannot pay that fee. Keep some AVAX in the wallet you connect, even if your whole trading balance is in WAVAX. AVAX pays C-Chain transaction fees; WAVAX is a token that represents AVAX. A swap may need a separate approval transaction before the trade. Check the wallet’s fee estimate and leave AVAX for any follow-up transaction. AVAX and WAVAX do different jobs AVAX is the C-Chain’s native coin, which means the network uses it to charge for transactions. WAVAX is a token designed to work with apps that accept standard tokens. One WAVAX represents one AVAX, but the two are not interchangeable when paying a fee. That distinction matters when you start using a wallet instead of a centralised exchange. The exchange may have handled network costs behind the scenes; with a wallet, your own AVAX balance covers them. If you are preparing a swap or looking for liquidity, how to use Blackh...

Cross-chain swap slippage for route comparers

Image
For a two-swap cross-chain route, a 0.5% slippage tolerance usually applies to each swap separately, so it does not guarantee the final amount stays within 0.5% of the original quote. If you are comparing routes, check where each minimum-output limit is enforced and what happens if a later leg cannot meet it. What does slippage tolerance protect? Slippage tolerance sets the largest adverse difference between a swap’s quoted output and the minimum output the transaction will accept. For a swap quoted to return 1,000 XYZ at 0.5%, the minimum is 995 XYZ; below that, the swap reverts instead of completing at the worse rate. The limit protects against price movement and state changes between quoting and execution, including other trades changing a pool’s reserves. It does not cover every change to the total value delivered: bridge fees, a bridge’s conversion rate, destination gas, and token transfer fees may be handled separately or incorporated into the quote. Also separate price impact ...
