# Backup web3 provider
|
|
|
|
Nimbus supports using multiple web3 providers, in case one breaks or goes down. These web3 providers must share JWT secret and will be used in a fallback manner, meaning that when the first one fails, the second one will be used instead until the first one is back up.
|
|
|
|
Each beacon node requires at least one dedicated web3 provider.
|
|
|
|
!!! note
|
|
The backup web3 provider must use the same JWT secret as the main provider, and will not be used until the main provider has failed. This may result in a gap in duties as the backup provider syncs. This gap will be addressed in future releases.

```sh
|
|
./run-mainnet-beacon-node.sh \
|
|
--web3-url="http://127.0.0.1:8551" \
|
|
--web3-url="ws://backup:4444"
|

```
