Definition
Wallet migration is the process of transferring cryptocurrency assets — including tokens, NFTs, and DeFi positions — from one on-chain address (the source wallet) to another (the destination wallet), without routing funds through a centralized exchange or custodian.
The term is sometimes used interchangeably with "wallet transfer," but migration typically implies a planned, multi-step process that may span multiple chains and asset types, rather than a single ad-hoc transaction.
Key Characteristics
Non-Custodial
In a proper wallet migration, no third party holds your private keys or takes custody of your assets at any point. You sign every transaction yourself. Your assets are always either in the source wallet or the destination wallet — never in an intermediary's account.
On-Chain
Every step of a migration is an on-chain transaction. The blockchain records each transfer permanently. There is no off-chain settlement layer.
Composable
A migration can include multiple operation types:
- Direct transfers — sending a token from address A to address B on the same chain
- Bridge operations — moving assets from one chain to another
- Swaps — converting one token to another as part of the route
Irreversible
Like all blockchain transactions, individual migration steps are irreversible once confirmed. This is why simulation and planning matter — mistakes cannot be undone.
