Sooth on Solana

Solana implementation of the Sooth Protocol — prediction markets that bond on an LMSR AMM in the deployment's instance token, graduate into an on-chain order book in USDC, and settle through a manual adjudicator with a veto window.

Companion to Tora-Build/sooth-alpha (the EVM home). Deployed to Solana devnet.

Layer	What it ships
packages/programs-core/programs/sooth-core/	sooth_core — one Anchor program: market lifecycle, LMSR AMM, CLOB, LP/fee flows, adjudication. No cross-program CPIs.
packages/sdk-solana/	@sooth/sdk-solana — instruction builders, account readers, PDA helpers, client-side LMSR quote math.
apps/demo/	Forked demo: classic pages, the Eastboard shell at /options, Arena at /play. Talks to the program via a chain-shim.

Where to start

You are…	Read first
A new contributor	HANDOVER.md — how the protocol works and where the code lives
Just want it running	docs/build.md
Checking what exists	docs/status.md — shipped surface, deployment, open items
Picking up the next task	docs/roadmap.md
An SDK integrator	packages/sdk-solana/docs/integrator-contract.md
Founder / decision-maker	docs/decision-log.md

Quick build

pnpm install
anchor build                             # Anchor 0.30.1, vendored anchor-syn patch
pnpm --filter @sooth/demo dev:localnet   # solana-test-validator path
# or
pnpm --filter @sooth/demo dev:surfpool   # Surfpool path (sub-second startup, time-travel cheatcode)

The seed script writes .env.local and a pre-funded test keypair, deploys sooth_core, bootstraps the protocol singletons, and serves vite on http://localhost:5175. pnpm dev without a flag targets devnet. Wallet setup is in docs/build.md.

Every transaction must prepend ComputeBudgetInstruction::request_heap_frame(256 * 1024) — the program runs a custom 256 KB bump allocator. The SDK adapter does this on all paths.
