Official BKN Smart Contract Migration Announcement

Official BKN Smart Contract Migration Announcement

Brickken is pleased to announce the upcoming migration of BKN to a new Ethereum smart contract.

This migration forms part of Brickken's ongoing infrastructure evolution and has been designed to strengthen the long term technical foundation supporting the BKN ecosystem.

The BKN ticker will remain unchanged. Token holders will receive 1 new BKN for every 1 existing BKN migrated.

Migration Date

The migration will commence on: 25 June 2026 at 13:00 UTC

Migration Window

The migration portal will remain available until: 25 July 2026 at 00:01 UTC

Token holders maintaining custody of their own wallets are encouraged to complete the migration before the end of the migration window.

Following the closure of the migration window, Brickken will communicate any additional procedures applicable to unclaimed tokens.

Migration Overview

The migration will take place on the Ethereum network.

Users holding BKN on supported centralized exchanges will not be required to take any action.

New BKN Contract

Contract Address: 0xFc209EeBA3D744aA741cc5C2A73Ebf9C977B5F82

Etherscan Contract: https://etherscan.io/address/0xFc209EeBA3D744aA741cc5C2A73Ebf9C977B5F82

Previous BKN Contract

Contract Address: 0x0a638f07acc6969abf392bb009f216d22adea36d

Etherscan Contract: https://etherscan.io/address/0x0a638f07acc6969abf392bb009f216d22adea36d

Following completion of the migration, the new contract will become the official BKN contract supported by Brickken.

The previous contract will no longer be supported for ecosystem integrations, staking, exchange connectivity, or future protocol developments.

Security Audit

The new BKN smart contract has been independently reviewed and audited by OpenZeppelin, one of the most trusted security firms in the blockchain industry.

The audit was conducted on the Brickken v2 token contract and the accompanying Migrator contract, both written in Solidity. OpenZeppelin's review covered the full scope of the migration infrastructure, including the ERC-20 implementation, permissioned minting system, burn functionality, gasless approvals, timestamp-based governance checkpoints, and the 1:1 migration mechanism.

The audit identified no Critical, High, or Medium severity issues. A total of 8 findings were reported, consisting of 5 Low severity issues and 3 Notes/Additional Information items. 7 of the 8 findings have been fully resolved, and the remaining item has been formally acknowledged with a planned resolution path.

OpenZeppelin's conclusion described the codebase as simple and well-written, with no major issues identified.

Supply Alignment

The original BKN Whitepaper published in September 2021 contemplated a total supply of 150,000,000 BKN.

The current issued supply is approximately 143,000,000 BKN.

As part of this migration, the supply framework is being aligned with the original whitepaper specification.

The difference of approximately 7,000,000 BKN will be reserved exclusively for ecosystem growth initiatives and will not be allocated to founders, investors, advisors, or treasury distributions.

These tokens are intended to support:

  • Staking rewards
  • Community incentive programs
  • Ecosystem growth initiatives
  • Future participation and engagement mechanisms

Centralized Exchange Support

Brickken has fully coordinated the migration with its centralized exchange partners.

MEXC and BitMart, the only centralized exchanges currently listing BKN, have confirmed their participation and support for the migration process.

Migration timing, account coordination, token allocations, and distribution procedures have been completed with both exchanges to ensure a smooth transition for token holders.

Users holding BKN on MEXC or BitMart will not be required to perform any manual migration.

The migration will be handled directly through the respective exchanges.

Any exchange specific deposit and withdrawal notices will be communicated by the exchanges through their official channels.

Self Custody Migration Portal

Users holding BKN in self custody wallets will be able to migrate their tokens through Brickken's official migration portal.

Migration Portal: https://www.brickken.com/staking

The portal will become available upon commencement of the migration process.

Staking Pool Migration

Brickken will directly migrate all BKN held within the official Brickken staking pool.

Official Staking Pool Address: 0x8F523d7e1acbBc6D0E3CA19B7D8C1981B346ceb8

Etherscan: https://etherscan.io/address/0x8F523d7e1acbBc6D0E3CA19B7D8C1981B346ceb8

Users participating in the official Brickken staking program will not be required to perform any additional actions regarding tokens held within the staking pool.

Important Security Notice

Users should only rely on information published through Brickken's official communication channels.

Brickken will never request private keys, seed phrases, wallet credentials, or direct transfers to personal wallets.

Users should verify all information through official sources before interacting with any migration interface.
