Self-custodial wallets
Desktop, mobile, and browser wallets where keys never leave the user. Hardware wallet integration, deterministic key derivation, and secure signing pipelines.
Blockchain engineering
Self-custodial wallets,
built to expose what makes each chain unique.
Bisoncraft is a blockchain development studio specializing in self-custodial wallets written in Go and TypeScript. We go beyond send-and-receive — surfacing staking, privacy, governance, and the protocol-native features generic wallets leave behind.
What we do
Staking & delegation
First-class support for validator selection, delegation, rewards, slashing awareness, and unbonding windows — surfaced as real UX, not afterthoughts.
Privacy features
Shielded pools, stealth addresses, coin control, and selective disclosure — integrated where the network supports it, without compromising self-custody.
Protocol-native UX
Governance voting, on-chain identity, atomic swaps, network-specific account models — we expose what each chain actually does.
How we work
01
Go & TypeScript, end to end
Go for wallet cores, node-interfacing services, and cryptographic primitives. TypeScript for UIs, SDKs, and browser extensions. One team, one stack, no silos.
02
Self-custody without compromise
No custodial shortcuts, no key escrow, no "trusted" middleware. Architectures that stay honest even when features get ambitious.
03
Deep per-network support
We read the specs. Each supported chain gets purpose-built integration that respects its account model, fee mechanics, and native capabilities — not a lowest-common-denominator abstraction.
04
Security as a discipline
Threat modeling, deterministic builds, reproducible releases, careful dependency hygiene, and a bias toward boring, reviewable code.
Let's build something.
