Contribution Preview
What contributing will look like
A preview of the planned contributor experience — campaign goal, ADA/USD estimate, fees, and return conditions — before any real contribution exists.
Contribution transaction planning
A planning map only. It shows where things stand and what a future contribution flow would require. No transaction is built, signed, or submitted; no ADA is requested; no funds move.
Transaction design proposal prepared. An architecture-only design for a future contribution flow exists (lifecycle, strategy options, risk register, and gate sequence). Design only — no transaction build, no signTx, no payment address, and no funds. Nothing here is enabled.
Funding address strategy proposal prepared — no payment address is active. An architecture-only proposal covers address options, custody policy, chain observation, and emergency-stop requirements. No payment address, no QR code, and no funds. Nothing here is enabled.
Pre-funding implementation architecture prepared. Funding address implementation, chain observer design, contribution candidate lifecycle, and emergency-stop designs exist as proposals. Still no payment address, still no QR, still no funding activation. Design only — nothing here is enabled.
Testnet/preprod funding rehearsal architecture prepared. A testnet/preprod funding implementation proposal, a fail-closed activation design, and a rehearsal runbook exist. Still no payment address, still no QR, still no funding activation. Design only — any future rehearsal would be testnet/preprod-only and clearly labelled.
Disabled testnet funding config exists — funding still not active. A disabled testnet/preprod config (masked address only) is prepared. Still no payment address shown, still no QR, still no funding activation.
Compliance/KYC architecture planned — no identity documents are collected. A privacy-first KYC/KYB readiness design exists for possible future funding. No personal data, no documents, no provider integration, and no funding are enabled.
Observer dry-run readiness — no chain payments are observed or recorded. The ContributionObservation table exists for candidate data (public chain candidate data only — never a Contribution, testnet and redacted). The observer is not live: no external API call, no chain query, no address/UTxO scan. Any candidate row is recorded only through one guarded testnet helper. No payment address, no QR, no funding activation. This campaign is still not accepting support.
Observer candidate dry-run prepared — simulated only, no chain query, no DB writes. An admin readiness view shows deterministic in-memory sample candidates (redacted). Nothing is observed or stored; no payment address, no QR, no funding activation.
Observer provider readiness prepared — no provider API calls are made. Provider environment presence may be checked (values never shown); no Koios/Blockfrost/Ogmios call, no live observer, no DB writes, no funding activation.
Current state (live database)
The campaign is a non-fundable DRAFT and is not accepting support. Interest and proof are tracked separately from real funding — the contribution, wallet, and settlement counts stay at 0.

Wallet readiness
A contribution would later start from a connected wallet on a supported network. This panel reflects your shared wallet connection — it is read-only and creates no contribution. Real funding stays disabled.
Wallet readiness
Not connectedNo wallet connected yet.
Contribution preview only — No ADA is sent, no transaction is signed, and no contribution record is created.
Why contribution intent matters
Before sending anything, a contributor should understand exactly what they are backing and on what terms.
See the campaign goal
A contributor sees the USD goal a builder is raising toward before committing anything.
See an estimated ADA/USD value
Contributions are in ADA against a USD goal, so an estimated value at the current oracle rate keeps it legible.
Understand the fee and Reserve model
A contributor sees how the success fee is allocated, including the Builder Reserve share.
Understand refund / return conditions
If a campaign falls short of its goal at close, contributions are intended to be returned. That should be clear up front.
See oracle, stable-value, and governance differences
Normal campaigns settle by oracle and may use stable-value protection; governance deposit pools keep ADA as ADA.
The planned flow
Each step is Planned or Later. None of it runs today.

This panel is a static preview. No wallet is connected, no ADA is sent, and nothing is submitted.
Future contribution → settlement flow
How a real contribution would eventually flow, mapped to the swap architecture. Every step below is future and disabled — only previews exist today. No live swap, no transaction built/signed/submitted, no funds, no custody, no settlement, no payment processing.

Cardano Builders Fund never asks for your seed phrase or private keys. A contribution intent records nothing on-chain and moves no funds.
