RenBridge LPs should read their pool’s current mix, then choose the available withdrawal that leaves them least renBTC at acceptable slippage, if the pool offers single-asset or imbalanced exits. RenBridge minted renBTC through RenVM before its 2022 sunset; later selling often left pools heavy in renBTC, so your original deposit does not predict your withdrawal.
Why RenBridge Pools Became Heavy in renBTC
Many pools accumulated renBTC when holders swapped it for the other BTC-type tokens in those pools after the bridge’s sunset. A swap gives the trader the token they want and leaves the renBTC they sold in the pool. Repeated swaps can drain the other reserves while increasing the renBTC reserve. An LP still owns a share of the pool, but that share now represents a different mix of assets.
The RenBridge shutdown matters here because withdrawing renBTC is not the same as recovering native Bitcoin. renBTC is a wrapped token on another chain, and the original service that minted and burned it was sunset. Treat any renBTC in a withdrawal quote as an asset you may have to hold or dispose of separately. The pool’s current balances and withdrawal quotes, rather than the amounts you deposited years ago, show what your LP tokens can return now.
Find the Pool and Free Your LP Tokens
Start with the LP token or gauge position in your wallet and identify its pool and chain. The token name alone may be ambiguous: use its contract address and the position shown by the pool or farm to match it to the underlying tokens. You need wallet access and enough of that chain’s native gas token for the transactions that follow.
If your LP tokens are staked in a gauge or farm, unstake them first. A gauge holds the LP tokens while you earn rewards; seeing a staked balance does not mean those tokens are available for the pool’s withdrawal transaction. Claim rewards if you intend to, then use the gauge’s withdrawal action and wait for the LP tokens to appear in your wallet. If the interface offers a combined unstake-and-withdraw action, inspect its quoted outputs before signing it.
Open the matching pool page and confirm that its listed assets include renBTC. Then find its current balances, your LP balance, and the withdrawal choices it actually offers. The choice described below applies only where you can withdraw one asset or specify an imbalanced mix. If the pool offers proportional withdrawal only, that pool mix determines the assets you receive.
Read the Balance Mix Before Choosing an Exit
The current pool proportions estimate your renBTC exposure from a proportional withdrawal. If renBTC accounts for most of the pool, burning LP tokens proportionally will return mostly renBTC, along with smaller amounts of the other tokens. Look at the actual token amounts in the withdrawal preview as well as any percentage display: a percentage of pool value may differ from a percentage of token units when the assets no longer trade at the same price.
A token balance associated with the RenBridge Bitcoin bridge remains renBTC when it leaves the pool. Withdrawing liquidity does not unwrap it into Bitcoin or turn it into the other BTC-type asset you originally supplied. That distinction is especially useful when an old position shows a familiar LP token quantity but the pool’s reserves have changed substantially.
Use the amount of LP tokens you plan to burn when comparing quotes. A small test withdrawal and a full exit can have different results, particularly if your position is large relative to the pool’s remaining reserve of the token you want. Refresh the pool page before signing, since swaps by other users can change both the balance mix and your quote.
Compare Proportional and Single-Asset Withdrawals
A proportional withdrawal returns each token in roughly the pool’s current mix; a single-asset withdrawal aims to return only the token you select. If an imbalanced withdrawal is available, it lets you request a chosen combination. Preview each available option for the same LP amount, then compare the renBTC quantity and the amount of usable BTC-type tokens you would receive.
Single-asset withdrawal can eliminate renBTC from the immediate payout, but it may be costly when the desired token is scarce. The pool effectively has to exchange your share of the other assets into that token. Taking more of a depleted reserve can move the pool farther out of balance, worsening the rate and adding fees. The quoted output may therefore be much lower than the number of BTC-type units suggested by your LP share.
Separate that cost from execution slippage. The quote already reflects the pool’s pricing and fees; the slippage setting limits how much worse the transaction may execute if conditions change before confirmation. Raising that limit does not improve a poor quote. Compare the quoted amounts themselves, then set a minimum received amount you would still accept.
Choose the withdrawal that leaves you least renBTC at a cost you accept. That could be a single-asset exit, an imbalanced exit that takes a small amount of renBTC, or even a proportional exit if the alternatives consume too much value. The best choice depends on the pool’s live reserves, your position size, and the quoted outputs, not on a fixed rule that one withdrawal button always wins.
Confirm What You Received
A completed exit turns your LP tokens into the assets shown in the confirmed withdrawal, which may include renBTC. After the transaction settles, compare the received amounts with the preview and confirm each token’s contract address in your wallet. A familiar ticker or token image is not enough to establish which asset arrived.
For a full exit, verify that your pool LP balance is zero and that no LP tokens remain staked in the gauge. If either balance remains, the position is still partly open. Keep the transaction record and the final token amounts together so you can tell how much renBTC exposure you actually removed and how much, if any, remains in your wallet.
Once the LP position is closed, assess the BTC-type tokens you received for your intended use or route to Bitcoin. That next decision should establish which of those assets you can actually use, and what it would cost to move or exchange any remainder.
