Smart Contract Development

CryptoLions provides specialised smart contract development services for Antelope (EOSIO) blockchains, with deep expertise in C++ contract authoring built through years of hands-on ecosystem contribution since the EOS genesis in 2018.

Service Overview

As creators of the SimpleAssets NFT standard — one of the most widely adopted smart contract standards in the Antelope ecosystem with 106+ GitHub stars and 60+ forks — CryptoLions has demonstrated ability to design, build, and deploy production-grade on-chain logic at scale. Their smart contract work spans token standards, governance, game logic, and DeFi primitives across EOS/Vaulta, WAX, Ultra, and Telos chains.

What's Included

• Token Standards — Fungible tokens (FT), non-fungible tokens (NFT), and non-transferable tokens (NTT) contract development, including the SimpleAssets standard
• Governance Contracts — Multi-signature, DAO, and voting contract implementations
• Game Logic — On-chain game mechanics and NFT asset interactions (as demonstrated in Kolobok Adventures)
• DeFi Contracts — Financial primitives and protocol-level smart contract development
• Custom Business Logic — Enterprise and protocol-specific contract requirements
• Deployment and Testing — Testnet deployment using the Jungle Testnet (maintained by CryptoLions) and mainnet launch support
