Solana, EVM, wallets

On-chain when it
earns its place.

Solana for throughput and fees. Ethereum and L2s for composability. Wallets that hide the seed phrase from your users until they want it. We built the Hive on this stack ourselves.

The stack

The tools we reach for.

Solid line: what we use every day. Dashed line: what we reach for when the brief justifies it. We will work in your stack if you have a strong reason; otherwise these defaults serve us well.

How we engage

Four steps. Real demos every Friday.

From signed SOW to first demo is one week. No discovery loops that bill for months without showing software. No silent stretches between status decks.

01

Chain selection

Solana vs EVM. Mainnet vs L2. We pick by engineering constraints, not narrative.

Week 0
02

Contracts

Foundry / Anchor tests. Property-based testing. Formal verification for high-value paths.

Week 1-6
03

Wallet + auth

Embedded wallets, gasless UX where possible, key recovery story.

Week 2-6
04

Audit + launch

Internal review + external audit. Monitoring + pause switch live before mainnet.

Week 6+
Plutobee shipped our Solana mint of 100K cNFTs in 8 weeks. Total on-chain fees under $80. The contract has been audited and is live.

Frequently asked

The questions buyers ask first.

Solana or Ethereum?
Solana for throughput, low fees, consumer use cases (gaming, NFTs, payments). Ethereum + L2s for DeFi, composability, deep liquidity. We pick per project, not per ideology.
Do you do audits?
Yes, internal review with Foundry + property tests. For mainnet launches with real value at risk we recommend a third-party audit and we coordinate with the firm.
Can users pay without crypto?
Yes. Stripe + USDC settlement on the back end. Apple Pay / Google Pay on the front. The user experience matches a normal app; the chain is invisible until they want it.
What about regulation?
We handle KYC vendor integration (Persona, Sumsub), AML screening, and Travel Rule compliance. Legal sign-off is owned by your counsel; we make their job easy.

Ship on-chain.
Without the noise.

Senior blockchain engineer reads your idea and tells you which chain (and whether you actually need one).

Frequently asked

Quick answers.

The questions buyers in this service ask in week one.

Solana or EVM?+

Solana for high-throughput consumer experiences, compressed NFTs, real-time settlement. EVM for liquidity-rich DeFi and Ethereum-native ecosystems.

Do you do smart contract audits?+

Yes via partners (Trail of Bits, Sigma Prime, ConsenSys Diligence) for high-stakes contracts. Stinger does our own pre-audit for non-financial contracts.

How do you handle key management?+

HSM-backed signing for production. Multi-sig for governance. Hardware wallets for human-signed transactions. Never plaintext keys, ever.

Can you support stablecoin payments?+

Yes. USDC on Solana, Ethereum, Polygon, Base. Settlement reconciliation. Off-ramp integration with Circle, Stripe.

What about OFAC and compliance?+

Wallet screening via Chainalysis or TRM Labs. Sanctioned-address blocking at smart contract level for permissioned products.
