BigTR Coin: smart contracts and pre-sale infrastructure.
We developed the smart contracts behind BigTR Coin, a fixed-supply BEP-20 token and an eight-stage pre-sale, and the wallet-based sales app that runs on them. The pre-sale contract has been audited independently by Cyberscope.
Written to be checked, not trusted.
BigTR Coin is the shared digital asset of the BigTR ecosystem, whose first product, the BigTR app, is live on iOS and Android. Our part is the code that holds the value: contracts anyone can read, verify and audit.
Six pieces, one audited system.
From the token contract to the wallet a buyer connects, every piece is on-chain or open to inspection.
Token contract
Fixed-supply BEP-20 with no minting, no owner, no pause, no blacklist and no transfer tax. The source code is verified on BscScan.
Pre-sale contract
Eight quota-based price stages; every purchase is recorded on-chain against the buyer’s wallet. Two-step ownership transfer, an emergency pause and re-entrancy protection.
Sales app
Buyers connect MetaMask, Trust Wallet or any WalletConnect wallet, or sign in with e-mail and get a wallet created for them.
Multisig treasury
Payments settle to a Safe wallet that needs two of three signatures, so no single person can move the funds.
Independent audit
Cyberscope reviewed the pre-sale contract in three rounds between July and August 2026: no critical or medium findings.
Open to inspection
Contract addresses are published on the project site, and anyone can check every transaction on BscScan.
