:megaphone: MAINNET Upgrade v1.7.14

Dear Klever @Validators ,

We are thrilled to announce the release of a major Klever Blockchain upgrade that brings powerful advancements across tokens, smart contracts, security, and performance. This release is a milestone that will not only enhance developer flexibility but also strengthen network resilience and scalability for the entire ecosystem.

:sparkles: Why this matters:

  • Developers now have Semi-Fungible Token (SFT) support, cross-VM contract execution, and enhanced asset management tools.

  • Smart contracts gain new powers: royalties processing, raw argument execution, and more efficient deployment and deletion handling.

  • Critical security patches reinforce protection against vulnerabilities and malicious validators.

  • Infrastructure and consensus improvements ensure smoother performance, stronger reliability, and a more scalable future for Klever Blockchain.

This upgrade is mandatory and requires immediate action from all validators to stay aligned with the network.

:alarm_clock: Deadline:
Please upgrade before epoch 4860 – Tuesday, 28 October 2025, 13:00:00 UTC.
Nodes not updated by this epoch risk forking from the network, and validators may be jailed.

:bulb: Make sure to update all configs files prior update the node.

:high_voltage: Upgrade Instructions:

  1. Download new config:
curl -k https://backup.mainnet.klever.org/config.mainnet.108.tar.gz | tar -xz -C ./node
  1. Download new image version:
docker pull kleverapp/klever-go:v1.7.14-0-g22769b30
  1. Update directory permissions:
chown -R 999  $(pwd)/node
chown -R 999  $(pwd)/node/config
chown -R 999  $(pwd)/node/db
chown -R 999  $(pwd)/node/logs

Stop and remove your current node:

docker stop klever-node && docker rm klever-node
  1. Run your node again:
docker run -it -d --restart unless-stopped \
    --user "999:999" \
    --name klever-node \
    -v $(pwd)/node/config:/opt/klever-blockchain/config/node \
    -v $(pwd)/node/db:/opt/klever-blockchain/db \
    -v $(pwd)/node/logs:/opt/klever-blockchain/logs \
    --network=host \
    --entrypoint=/usr/local/bin/validator \
    kleverapp/klever-go:v1.7.14-0-g22769b30 \
    '--log-save' '--use-log-view' '--rest-api-interface=0.0.0.0:8080'

:fire: This is one of the most exciting and impactful updates in Klever’s history, and your role as a validator is crucial in making it a success. Together, we are building a faster, safer, and more innovative blockchain for everyone.

Let’s move forward. Stronger, smarter, and more Klever than ever! :purple_heart:
