jup.sh 0.1.0-alpha.0

jup.sh 0.1.0-alpha.0 Release Notes

Status: GitHub pre-release.

Release date: 2026-05-09.

This is the first alpha checkpoint for jup.sh.

It is a source-run developer alpha, not a production payment system.

Summary

jup.sh is exploring:

Risk and settlement for Solana agent payments.
Agents pay with any verified token. Recipients settle in USDC. Policy decides
when humans step in.

This alpha turns that direction into a local CLI and static Risk Review flow.
It does not move funds.

What Is Included

• Static pay.sh-inspired jup.sh website.
• Rust workspace for reusable payment intent logic.
• Local CLI command:

jup-sh pay --agent claude --token SOL --settle 20 USDC

• Local deterministic policy checks.
• Local payment intent persistence under .jup-sh/intents.
• Mock settlement quotes.
• Optional Jupiter quote-only settlement estimates:

jup-sh pay --agent claude --token SOL --settle 20 USDC --quote-provider jupiter

• Quote-aware policy checks:
  • quote_available
  • quote_settlement_token
  • quote_price_impact
• Risk Review URL export:

jup-sh intent export intent_xxx

• Static Risk Review page that can render exported intent payloads.
• Agent-facing JSON output:

jup-sh pay --agent claude --token SOL --settle 20 USDC --json

• Agent-facing pay exit codes:
  • 0 = auto_pay
  • 2 = review_required
  • 1 = rejected or command failure
• CLI JSON contract documentation:

docs/cli-json-contract.md

• Private npm alpha wrapper prototype:

npm run cli:alpha -- pay --agent claude --token SOL --settle 20 USDC

• Smoke tests and npm package dry-run checks:

npm run alpha:smoke
npm run alpha:pack

What Is Not Included

• No wallet signing.
• No swap execution.
• No Solana Pay transaction request generation.
• No custody of funds.
• No remote backend persistence.
• No authentication.
• No published npm package.

Verification

Verified before tagging:

npm run check
npm run alpha:smoke
npm run alpha:pack
cd rust && cargo test --workspace

Expected npm run alpha:pack package contents:

README.md
bin/jup-sh
package.json

Notes

jup.sh is an independent community-built tool and is not affiliated with
Jupiter.

This alpha intentionally keeps signing and money movement out of scope. The
purpose is to harden the first agent-facing contract: local intent creation,
policy decisioning, quote-aware review, and exportable Risk Review payloads.
