Launchpad and pool migration design

A migration diagram can imply guaranteed liquidity even when custody, allocation conversion or pool creation can fail. The phase map should expose those dependencies before any real action.

Describe a finite sequence of states: requirements draft, allocation accepted, migration eligibility, pool construction and post-migration reconciliation. Each transition needs prerequisites, authority, evidence and a failure destination. A launchpad or bonding-curve label does not establish the contract formula, reserve behavior or migration permissions. Do not assume that reaching a displayed threshold guarantees a tradable pool.

Maintain invariants across the proposed boundary: exact asset identity, compatible raw units, supply accounting, reserve custody and destination controls. Migration may convert claims or move balances; the design must state who authorizes it and how users can inspect the resulting state. If a failure leaves funds inaccessible, say so explicitly in the plan rather than drawing a reversible arrow that the implementation may not support.

All phases here are hypothetical. No reserve is funded, no wallet signs, and no deployment or pool is created. A transparent migration design is still a design, not an observed launch or a promise of price and liquidity.

Transition gate: evidence required to move between states.

Invariant: condition that must remain true across a transition.

Failure state: defined result when prerequisites or execution fail.

Rollback limit: what cannot be automatically reversed.

ILLUSTRATIVE Cedar uses draft state S0, eligibility S1 at a stipulated paper threshold, proposed pool S2 and reconciled S3. S1→S2 requires exact token identity, reserve accounting and destination permission review. If destination creation fails, state F retains a documented unresolved custody obligation. No balances or actual threshold observations exist.

Bonding-curve/migration specification with hypothetical states S0–S3, gated arrows and visible F failure lane. Do not plot an invented real price curve; annotate formula and reserves as unimplemented assumptions.

SPECIFICATION_ONLY — the rendered visual has not been produced or independently reviewed.

The fictional state machine exposes prerequisites and a failure branch. It supports review of the proposed flow without executing it.

It proves no deployed launchpad formula, successful migration, funded reserves, automatic refund, executable rollback or future pool availability.

Skipping reconciliation after pool creation; drawing guaranteed refunds without a mechanism; equating threshold reached with completed migration; hiding custody during failure.

Write transition rows S1→S2 and S2→S3. Add one failure branch and three invariants. Rewrite “migration is automatic and liquidity is guaranteed.”

• Name phases and responsible controls.
• Attach acceptance evidence to each transition.
• Show failure custody and rollback limits.
• Reconcile destination identity and withdrawal controls.

A migration plan is inspectable only when its transition conditions, invariants and failure custody remain visible.

• Thresholds do not prove completed migration.
• Failure branches must preserve custody obligations.
• Rollback is an implementation claim, not a diagram convention.

Use the named ZECOIN tool only as an evidence-reading context. This lesson creates no tool output, account session or entitlement. Offline exercise; do not sign, deploy, approve or fund anything.

• POOL: Uniswap v2 pools — LP tokens represent pool participation; withdrawal mechanism is separate from motive or fraud. Boundary: Mechanism documentation only; original illustrative values are stipulated, not observations. Historical records have separately frozen provenance and explicit collection gaps.
• ERC20: ERC-20 standard — Token interface and allowance semantics; the standard does not establish issuer identity or safe permissions. Boundary: Mechanism documentation only; original illustrative values are stipulated, not observations. Historical records have separately frozen provenance and explicit collection gaps.
