Migrate your TCu29 from BNB Chain to Ethereum
A user guide to the 1:1 TCu29 migration. Read this before you connect a wallet.
Holding on Phemex or another CEX
No action needed
Your balance is migrated automatically and credited as Ethereum TCu29. There's nothing for you to do.
Holding inside a DeFi position (LP)
Unwind first
Withdraw the underlying TCu29 to your wallet first, then run the migration.
Self-custody wallet
Action required
MetaMask, Rabby, Trust, hardware: you must run the 4-step migration yourself before the window closes.
Before you start
- The wallet that holds your TCu29 on BNB Chain
- A small amount of BNB for gas on BNB Chain (covers Approve + Migrate)
- A small amount of ETH for gas on Ethereum (covers Claim)
- Confirmation that the destination address is one you control on Ethereum. If your BNB-Chain address is a smart contract (Safe, Argent, etc.), the same address on Ethereum may have different signers, so double-check before migrating.
Security sanity checks
- The site URL exactly matches the one published in official channels
- The contract address shown in your wallet matches the bridge contract address published in the official announcement
- Your wallet shows you on BNB Chain (chain ID 56) for the first two steps
- You are not being asked for a seed phrase. The flow only ever asks for transaction signatures.
Beware of phishing sites
Only use the official URL announced by TCu29. Beware of phishing clone sites that may appear in an attempt to scam you. Bookmark the real one and ignore everything else, including DMs, ads, and 'support' links.
The migration, step by step
The site shows a progress bar at the top: Connect → Approve → Migrate → Claim.
- 01
Connect
BNB ChainOpen the migration page and connect your wallet. The site detects your TCu29 balance on BNB Chain automatically.
- 02
Approve
BNB ChainA one-time on-chain approval that lets the bridge contract move your TCu29 out of your wallet. You only do this once.
- Spender = the official TCu29 bridge contract.
- Amount = your balance (avoid unlimited approval unless you understand the trade-off).
- 03
Migrate
BNB ChainLock your TCu29 on BNB Chain. Your BNB Chain balance drops to zero and the lock is recorded on-chain for verification.
- 04
Claim
EthereumOnce the relayer confirms your lock, switch your wallet to Ethereum and claim the equivalent amount of ERC-20 TCu29.
Key things to know
Same address, both sides
Your Ethereum claim is allocated to the same address you migrated from.
Mind your wallet type
EOAs (MetaMask, Ledger, Trezor) work the same on both chains. Smart-contract wallets (Safe, Argent) may not, so confirm your signer setup on Ethereum first.
Order and chains matter
Approve and Migrate must happen in order on BNB Chain (chain ID 56). Claim happens on Ethereum (chain ID 1), any time after the lock confirms.
It's a lock-and-claim, not a swap
It's not a swap. It's a 1:1 lock-and-claim. No slippage, no price impact, no AMM.
Timeline & deadline
The migration window opens May 15, 2026 and closes around August 13, 2026. We recommend completing your migration at least a week before the deadline to avoid network congestion.

On a centralised exchange like Phemex?
Phemex and other CEX partners migrate user balances automatically. There's nothing for you to do. The four steps above are only for self-custody and DeFi holders.
Troubleshooting
Track your migration
The Bridge Scanner shows relayer status and lets you verify any lock or claim.
