Comprehensive assistance for building on the Oasis Network: Sapphire confidential EVM ParaTime, ROFL (Runtime OFfchain Logic) applications, Oasis CLI, SDK development, and ParaTime operations.
Use this skill when the user mentions: "oasis", "sapphire", "sapphire paratime", "rofl", "oasis cli", "oasis sdk", "oasis network", "confidential evm", "oasis-sdk", "sapphire-paratime", "oasisprotocol", "oasis rofl", "paratime", "emerald", "cipher", "rose token", "oasis wallet", "sapphire contracts", "oasis node", "oasis core".
Also activate when the user is working in repos: oasisprotocol/sapphire-paratime, oasisprotocol/oasis-sdk, oasisprotocol/cli.

| Developer wants to... | Action |
|---|---|
| Create a Sapphire dApp | Use Hardhat + @oasisprotocol/sapphire-hardhat plugin |
| Build a ROFL app | oasis rofl init, oasis rofl create, oasis rofl build, oasis rofl deploy |
| Check account balance | oasis account show <name> |
| Transfer tokens | oasis account transfer <amount> <to> --network testnet --paratime sapphire |
| Deposit to ParaTime | oasis account deposit <amount> --network testnet --paratime sapphire |
| Withdraw from ParaTime | oasis account withdraw <amount> --network testnet --paratime sapphire |
| Manage ROFL secrets | oasis rofl secret set <NAME> - (pipe value via stdin) |
| View ROFL logs | oasis rofl machine logs |
| Check ROFL status | oasis rofl machine show |
| Inspect a ParaTime block | oasis paratime show <round> --network testnet --paratime sapphire |
| Use Go SDK with Sapphire | Import sapphire "github.com/oasisprotocol/sapphire-paratime/clients/go" |
| Use JS/TS with Sapphire | npm install @oasisprotocol/sapphire-paratime |
| Verify ROFL origin on-chain | Subcall.roflEnsureAuthorizedOrigin(roflAppID) in Solidity |
ParaTimes are parallel runtimes on Oasis. Key ones:
Sapphire provides end-to-end encryption for smart contracts:
Containerized off-chain applications running in TEEs, managed via Sapphire:
appd REST API for key generation, transaction signing, and queries| Network | Decimals | Symbol |
|---|---|---|
| Consensus (Mainnet/Testnet) | 9 | ROSE / TEST |
| Sapphire / Emerald | 18 | ROSE / TEST |
| Cipher | 9 | ROSE / TEST |
For deep dives, consult these references:
| Reference | Content |
|---|---|
| CLI.md | Complete CLI command reference: wallet, account, network, paratime, ROFL, transactions |
| SAPPHIRE.md | Sapphire ParaTime development: EVM patterns, SDKs (Go, JS/TS, Python), Hardhat, confidential contracts |
| ROFL.md | ROFL framework: app lifecycle, containers, secrets, appd API, deployment, proxy configuration |
| SDK-CORE.md | Oasis SDK and core concepts: architecture, ParaTimes, staking, consensus, cryptography |
If using Go SDK, always use backend.Transactor(senderAddr) for TransactOpts. Forgetting this sends transactions unencrypted.
For JS/TS, ensure @oasisprotocol/sapphire-paratime wraps the provider before any contract interactions.
compose.yaml (e.g., docker.io/library/python:3.12-alpine)Verify request body matches expected format. Check required fields: kind for keys, tx structure for sign-submit.
Sapphire/Emerald use 18 decimals, consensus uses 9. Wrong decimals = wrong token amounts. Always verify with oasis paratime list.
Add to .cargo/config.toml:
[build]
rustflags = ["-C", "target-feature=+aes,+ssse3"]
When helping with Oasis development:
Consult external AI council (Gemini 3.5 Flash, Codex, Qwen, GLM-5.2, Kimi) for thorough reviews and consensus-driven decisions. Use ONLY when explicitly invoked with "/council" or when user says "consult the council", "invoke council", or "council review". Do NOT auto-trigger on generic phrases like "thorough review".
PR babysitter: monitors CI status, auto-rebases when behind, auto-fixes CI where possible, delegates review comment handling to dlc:pr-check, and re-requests review after fixes. Designed for /loop usage with Remote Control.
Council review reference data — expertise weights, structured response format, scoring thresholds, and false positive taxonomy. Background knowledge for council subagents.
Audit review checklist for a repo: cluster recurring review-comment themes across merged PRs in a window, diff against docs/code-review-checklist.md, and open a PR proposing new entries with PR traceability. Designed for /schedule monthly cadence. Pass --dry-run to print clusters without opening a PR. Trigger phrases: audit review checklist, update review checklist, cluster PR findings.
Multi-agent development workflow using Agent Teams. Supports five modes: plan (architect teammate + PM teammate debate → plan.md), dev (developer teammate + code-tester teammate + qa-tester teammate + reviewer teammate iterate → code), full (plan → approval gate → dev), auto (plan → dev, no gate), and bugfix (tester + developer + reviewer TDD triad → fix + PR). Use when tasks benefit from collaborative agent teammates with peer messaging.
You MUST use this skill before /pm when work is ambiguous, scope is unclear, or multiple approaches exist. Explores problem space, proposes 2-3 approaches with trade-offs, and produces an approved spec document that feeds into both issue creation (/pm) and implementation planning (/cdt). Triggers: brainstorm, explore idea, think through, design approach, what should we build, explore options, weigh approaches, compare solutions, needs help deciding between alternatives.
