ICON Integration Update – September 2022

Welcome to the Integration Update series. In September, the teams made progress on ICON Bridge integrations for Binance Smart Chain, NEAR and SNOW.

Follow along for an itemized update of the work that has been done.

Binance Smart Chain:

The ICON Bridge integration with Binance Smart Chain has gone smoothly and the team has continued to patch recommended fixes and increase code testing coverage to 80%. Progress continued on building a usable centralized bridge for the BTP Relay System that can deliver digital assets between multiple chains.

NEAR Protocol:

In September, the team improved BMR Performance significantly, with up to 50x improvement in Block Monitoring. They also added Blacklisting and Transfer Restriction in BTS Contracts and began integration with Nexus.

SNOW Network:

SNOW's integration is in full flight with the goal of shipping to mainnet by the end of the month. Please note the current deployment will not include integration to Nexus. When live on mainnet, dapps will be abe to integrate what functions they want to use via their dapp itself.
