Prepare for and the upcomming chain upgrade using Cosmovisor.
#Upgrade
ⓘ  Â
Since we are using Cosmovisor, it makes it very easy to prepare for upcoming upgrade.
You just have to build new binaries and move it into cosmovisor upgrades directory.
#Download and build upgrade binaries
# Clone project repository
cd $HOME
rm -rf union
git clone https://github.com/unionlabs/union union
cd union
git checkout v0.25.0-rc4
# Build binaries
make build
# Prepare binaries for Cosmovisor
mkdir -p $HOME/.uniond/cosmovisor/upgrades/v15/bin
mv build/uniond $HOME/.uniond/cosmovisor/upgrades/v15/bin/
rm -rf build
Thats it! Now when upgrade block height is reached, Cosmovisor will handle it automatically!
Chain ID:
The unique identifier for the blockchain network.
union-testnet-9Latest Version:
The latest version of the chain software.
v0.25.0-rc4Github:
The Github repository hosting the code for the network in question.
Public endpoints
Public endpoints are rate limited but can be used for basic CLI usage, node syncing or testing environments. Request an API key for enhanced access limits, we offer free trial periods of 14 days and cheap shared access plans from $50 a month.
REST/LCD
REST endpoint for querying blockchain data through the REST framework. Often available for Cosmos chains but also the main framework for Aleo as an example.

RPC
Remote Procedure Call endpoint for the consensus client of a blockchain. This is not an EVM endpoint (we call this json RPC) but the main framework for blockchain frameworks like Cosmos, Aptos, Sui and Near.
testnet-rpc.lavenderfive.com:443/union
gRPC
High-performance RPC endpoint for blockchain communication using the Google gRPC framework. This is often standard gRPC and not the "WEB" framework which is sometimes also accesible.
testnet-union.lavenderfive.com:443
WebSocket
WebSocket endpoint for real-time blockchain updates of the consensus client. This is not the EVM websocket integration, we name and expose that separately. WS is commonly available for Cosmos and Move networks that also expose a REST endpoint.
