Solve & Cradle Studio: write a contract once, ship it to every major chain

Solve is Solieum’s smart-contract framework: programs written once in CradleScript are security-checked at build time and compiled by CRADLE into Solidity for every EVM network, a native Solana program, NEAR and Polkadot WASM, and Aptos and Sui Move. Cradle Studio is its web IDE.

Language and compiler design (CradleScript / CRADLE), multi-chain code generation, security analyzers, cost model and the Cradle Studio web IDE

Problem

Teams that ship on several chains maintain a separate codebase, toolchain and audit for each one, so contracts drift apart and every security fix has to be repeated. The goal was a single source that produces idiomatic code for each chain, blocks known vulnerability classes before anything is deployed, and shows the execution cost on each target at build time.

Architecture

CradleScript, Solidity or Rust sources are parsed into one chain-agnostic intermediate representation. Security analyzers run on that IR before lowering, and a high-severity finding stops the build, so one rule protects every target. A resource model estimates gas and compute units against each chain’s real limits. Back-ends then lower the IR to Solidity (EVM), a solana-program with real PDAs, rent and SPL CPI (SVM), near-sdk and ink! (WASM) and native Move for Aptos and Sui. EVM deployments use deterministic CREATE2 so a contract has the same address on every EVM chain. Conformance suites deploy to real validators in CI.

Solution

BitAzure engineered the CradleScript language and CRADLE compiler pipeline, the shared IR with its security analyzers and cost model, the per-chain code generators, the on-chain conformance suites that run in CI, and Cradle Studio, the browser IDE where developers write, compile and deploy CradleScript, Solidity and Solana programs.

Features

  • One CradleScript source compiled to EVM, Solana, NEAR, Polkadot, Aptos and Sui
  • Security analyzers on the IR that block the build on high-severity findings
  • Per-chain gas and compute-unit estimates before deployment
  • Idiomatic output per chain: PDAs and SPL on Solana, mappings and value transfers on EVM, native coins in Move
  • Deterministic CREATE2 deployment for one address across EVM chains
  • On-chain conformance suites for EVM and Solana enforced in CI
  • Cradle Studio web IDE with compile, terminal and chain selection

Outcomes

  • One codebase replaces a separate implementation per chain
  • Vulnerability checks run once on the IR and protect every target
  • Output is plain Solidity, solana-program, WASM and Move that each chain’s normal tooling can verify and audit
