Smart Contract Development
Through Smart Contract Development we create automated blockchain-based agreements, ensuring transparency, and accuracy.
Solicy builds crypto and blockchain wallets for exchanges, retail payment platforms, financial institutions, and NFT marketplaces. Whether you need a custodial wallet with compliance controls or a self-custody wallet for individual users, we handle the architecture, security, and multi-chain integration so your wallet fits how your business actually operates.
Not every wallet has the same job. A wallet for a crypto exchange has different requirements than one for an NFT marketplace or a retail payment app. We start by figuring out which one you're actually building.
We define whether you need a custodial wallet (where your platform manages keys, common for exchanges and institutions), a non-custodial wallet (where users control their own keys), or a hybrid model. This decision affects your compliance obligations, your liability, and how much control your users have.
We scope which chains and asset types the wallet needs to support: cryptocurrencies, NFTs, or both, across networks like Ethereum, BNB Chain, Polygon, and others. Multi-asset wallets need different token standard handling than single-asset ones, so this gets defined early.
For institutional and exchange wallets, we build in KYC and AML hooks, multi-signature approval flows, and audit logging. For consumer wallets, we focus on encrypted local key storage and biometric authentication. The security model follows the use case, not a one-size template.
We build the wallet and connect it to what it needs to talk to: payment gateways and fiat on/off ramps for retail products, exchange order books for trading platforms, or NFT marketplace contracts for collectible platforms.
We test transaction flows, key security, and integration points before launch, then stay on for monitoring, patches, and feature additions as your platform grows.
We build both models, so we recommend the one that actually fits your business instead of defaulting to whichever one we're more comfortable building.
Cryptocurrency, NFTs, or both. We build wallets that handle the token standards your platform actually uses, not just a single asset type.
From compliance-ready wallets for financial institutions to simple, fast wallets for retail crypto payments, we scope security and UX to match who's actually using it.
We connect wallets to fiat on/off ramps, payment gateways, and exchange infrastructure, so the wallet works as part of your broader platform, not as an isolated feature.
New chains, new asset types, new compliance requirements. We stay on after launch to build for what your wallet needs next.

Blockchain wallet development covers building the software that lets users or platforms store, send, and receive crypto assets or NFTs. It includes wallet architecture (custodial or non-custodial), key management, blockchain and token standard integration, and security features like encryption and multi-signature approval. Scope varies a lot depending on whether the wallet is for an exchange, a retail app, or individual users.
DeFi wallet development is a specific, narrower service focused on non-custodial wallets that connect users to DeFi protocols like lending and staking platforms. Blockchain wallet development is the broader category: custodial wallets for exchanges, retail payment wallets, NFT wallets, and institutional wallets, in addition to DeFi-focused ones. If your project is specifically a DeFi product, our DeFi wallet development services are the better fit; if you need a wallet for payments, an exchange, or NFTs, this is where that work happens.
Yes. We build multi-asset wallets that handle both cryptocurrency and NFTs, including the token standards NFT marketplaces rely on. If your platform needs to support both in one wallet, that gets scoped during the asset and blockchain planning stage.
Yes. Custodial wallets for institutions typically need KYC and AML integration, multi-signature approval workflows, and audit logging in addition to the core wallet functionality. We build these alongside non-custodial wallets, depending on what your business actually needs.
Cost and timeline depend heavily on wallet type. A single-asset, non-custodial wallet is the fastest and least expensive option, while a multi-asset custodial wallet with compliance features and exchange integration takes longer and costs more. Most projects range from a few weeks for a simple wallet to several months for a full institutional build. We give you a firm estimate after a discovery call.
We build wallets on Ethereum, BNB Chain, and Polygon, with support for additional chains scoped based on your project. If you need cross-chain asset support in a single wallet, we plan for that during the architecture phase.
