Do not send BTC through RenBridge in 2026: RenVM 1.0 no longer completes new bridge transfers. The interface may still appear online, but that does not mean the network can mint an asset on Ethereum or release BTC back to Bitcoin. RenBridge depended on RenVM and its Darknodes to authorize those movements; without that signing network, a page loading or a wallet connecting cannot complete the transfer.
- Check whether RenVM can still authorize a transfer.
- Check the exact asset and direction you intend to move.
- Check whether an old transaction is pending before taking action.
Check 1: RenVM must be able to authorize the transfer
A new RenBridge transfer needs RenVM to observe the source-chain transaction and produce the authorization that completes the other side. For BTC moving to Ethereum, that meant depositing BTC to the address generated for the transfer, waiting for Bitcoin confirmations, then having RenVM authorize minting the corresponding wrapped asset. If the signing network is offline, the deposit alone cannot make the Ethereum token appear.
Ren announced in November 2022 that it would sunset Ren 1.0: minting would be disabled first, burns would remain available for about 30 days, and the network would then shut down. That sunset was a response to the loss of its development funding and was intended to let holders redeem bridged assets during the wind-down. As of 20 October 2026, RenVM 1.0 is no longer an active transfer service, so there is no current RenBridge route for a fresh BTC deposit.
This is the check that decides whether to proceed: can the live protocol create and complete a transfer now? An old interface, a token listed in a wallet, or historical instructions are not proof of that capability. RenBridge’s former flow relied on RenVM signing; a front end can still display old options even when the network required to execute them is gone.
Check 2: The asset and transfer direction matter
RenVM’s old bridge handled transfers in both directions, but the two directions used different actions. A Bitcoin deposit was intended to mint a wrapped representation on a supported destination chain. To return to Bitcoin, a holder would burn the wrapped asset on its destination chain and specify a BTC address so RenVM could authorize release.
For example, if you wanted to move 0.05 BTC to Ethereum, the historic process would have required a RenVM-generated deposit address, enough Bitcoin confirmations, and a successful mint on Ethereum. Today, sending that 0.05 BTC to an old address does not restart the process or guarantee a matching token. Likewise, a burn transaction for a wrapped asset cannot by itself release native BTC if the network cannot sign the release.
Before considering any old instruction, identify the exact token contract and chain in your wallet, then determine whether the task is minting a wrapped token or redeeming one. A token with a Ren-related name can remain visible on-chain after its bridge has stopped operating; its presence does not show that it is redeemable. The direction and asset determine what was supposed to happen, but current protocol support determines whether it can happen.
Check 3: An old transaction needs its own status check
If you already sent BTC or submitted a burn, do not create a second transfer until you know what happened to the first one. Find the source-chain transaction ID in your wallet or block explorer and check whether it was confirmed. Then look for the expected destination event: a mint transaction on the destination chain for a deposit, or a BTC release transaction for a burn.
A confirmed Bitcoin deposit is not the same as a completed bridge transfer. If no corresponding mint appears, the BTC may have reached the old deposit address without RenVM completing the next step. Similarly, a confirmed token burn does not prove the BTC release occurred. Keep the transaction ID, deposit address, destination address, token contract, and any RenBridge transfer identifier together; those details are needed to distinguish a failed, incomplete, or completed transaction when asking a wallet provider or relevant community channel for help.
Do not send additional funds to an old deposit address, repeat a burn, or share your seed phrase with someone claiming they can recover the transfer. A recovery claim should explain how it will act on the specific on-chain transaction without asking for wallet secrets. If the bridge never completed its authorization, there may be no user-side button that can make it do so now.
In your place, I would treat RenBridge as unavailable for new BTC transfers, verify every old transaction on its source and destination chains, and use a currently operating route only after checking its supported assets and redemption path.
