* Eclair needs a _synchronized_, _segwit-ready_, **_zeromq-enabled_**, _wallet-enabled_, _non-pruning_, _tx-indexing_ [Bitcoin Core](https://github.com/bitcoin/bitcoin) node.
* You must configure your Bitcoin node to use `bech32` or `bech32m` (segwit) addresses. If your wallet has "non-segwit UTXOs" (outputs that are neither `p2sh-segwit`, `bech32` or `bech32m`), you must send them to a `bech32` or `bech32m` address before running Eclair.
* Eclair requires Bitcoin Core 26.1 or higher. If you are upgrading an existing wallet, you may need to create a new address and send all your funds to that address.

### Update minimal version of Bitcoin Core
With this release, eclair requires using Bitcoin Core 26.1.
Newer versions of Bitcoin Core may be used, but haven't been extensively tested.
With this release, eclair requires using Bitcoin Core 27.1.
Newer versions of Bitcoin Core may be used, but have not been extensively tested.
This version introduces a new coin selection algorithm called [CoinGrinder](https://github.com/bitcoin/bitcoin/blob/master/doc/release-notes/release-notes-27.0.md#wallet) that will reduce on-chain transaction costs when feerates are high.
To enable CoinGrinder at all fee rates and prevent the automatic consolidation of UTXOs, add the following line to your `bitcoin.conf` file:
```conf
consolidatefeerate=0
```
