Trace a wallet through a token migration by following its address across the old and new BEP-20 contracts, then reconciling migration events with transfers and balances at specific block heights. A token’s symbol or chart history can help identify a candidate, but neither proves that two contracts represent successive versions of the same asset.

• Old and new token contracts have separate transfer histories, even when the migration is 1:1.
• Use transaction logs and block heights to establish what the wallet did and when.
• Verify the migration rule before treating a new-token balance as a continuation of the old one.

Why does a migration split the history?

A migration usually moves or exchanges tokens between two distinct contract addresses. The old contract records activity up to the migration; the new contract records activity after tokens are issued or transferred there. Their BEP-20 balances and Transfer logs do not merge automatically, so a chart or wallet view for one address will not necessarily show the other contract’s history.

Think of the old and new contracts as separate account books. The migration transaction is the receipt connecting them, but its meaning depends on the contract code and the project’s stated terms: it might burn old tokens and mint new ones, transfer them to a migration contract, or let holders claim a replacement later. A proxy upgrade is a different case: if the token’s proxy address stays the same, the address history continues even if its implementation changes.

How do you trace the wallet across both contracts?

Start with the wallet address and the suspected old and new contract addresses. Identify the migration’s block range, then inspect the wallet’s transactions and token-transfer logs on both sides of that range. On BNB Smart Chain, a standard ERC-20-style transfer log identifies the emitting contract and includes indexed sender and recipient addresses; the token amount is in the log data and must be scaled by the contract’s decimals.

• Outgoing transfers from the wallet under the old contract.
• Transfers to a migration, burn, or treasury address.
• Incoming transfers or claims under the new contract.
• New-token transfers made by the wallet after migration.

For a fast visual cross-check, PooCoin analytics can help inspect BNB Smart Chain token price charts and wallet activity. Treat those views as a way to locate activity, then confirm the decisive migration transactions against the contract addresses and their logs; PooCoin cannot establish a project’s conversion terms from a matching symbol alone.

What proves the conversion, and what can mislead?

Reconcile amounts at block boundaries, not just by comparing current balances. For example, if a wallet sends 1,000,000 old tokens to a migration contract and later claims 900,000 new tokens at a stated 1:1 rate, the logs show 100,000 old tokens not yet accounted for by that claim. Check whether the remainder was claimed in another transaction, stayed in the old contract, or was subject to a cap or deadline.

Transfer logs show token movements, not the reason for them. A transfer to a contract does not prove that the contract accepts migrations, and a new-token transfer to a wallet does not prove it came from the old-token balance. Read the migration contract’s verified code or transaction input, and check the project’s published ratio, eligibility snapshot, and claim window. The key trade-off is speed versus certainty: an indexed wallet view is efficient for finding candidate activity, while transaction receipts and contract rules are needed to establish what the activity means.

FAQ

Does the same token symbol mean the new contract is genuine?

No. Symbols and names are not unique, and anyone can deploy a BEP-20 contract using familiar metadata. Verify the new contract address from the project’s official migration announcement, then confirm that its migration transactions and conversion terms match that source. A chart, logo, or wallet label is useful for discovery, not authentication.
