Hold mine closure funds in a regulator-visible escrow that releases only against independently verified land rehabilitation milestones. Regulators gain live visibility into whether the fund is sufficient and whether restoration work is genuinely progressing as claimed.
Turn an opaque provision on a balance sheet into a tracked escrow that pays out only for verified restoration.
01.
Open the vault to oversight. The Escrow and Conditional Settlement module holds the closure fund with the regulator holding a live read key, so authorities see the balance rather than trusting an annual statement.
02.
Pay for progress, not promises. Funds unlock in portions only when a rehabilitation milestone is marked complete, so no capital leaves the escrow ahead of the work it was set aside for.
03.
Trust the surveyor, not the operator. A milestone is released only after an independent verifier attests completion through Compliance Attestations, keeping the operator from certifying its own restoration.
04.
Check the fund against the liability. The contract tracks the held balance against the estimated closure cost, flagging any shortfall to the regulator long before the mine reaches end of life.
05.
Record every claim and check. Audit Logs seal each milestone claim, verification result, and disbursement with a time-stamp, building an unbroken history of how the fund was spent.
06.
Break closure into checkpoints. The rehabilitation plan is encoded as ordered milestones with defined evidence, so both operator and regulator work from the same restoration roadmap.
Follow a mine closure fund from deposit through a verified rehabilitation milestone to a controlled, evidence-based release.

Cerulea decomposes closure fund tracking into modular contracts. Each layer holds, claims, verifies, and releases against restoration milestones so that capital leaves escrow only for rehabilitation the regulator can see was done.
Milestone-gated fund escrow is a horizontal capability across regulated liabilities. Here is how different actors around mine closure put the tracked fund to work.
Hold live visibility into whether closure funds are sufficient and whether rehabilitation is genuinely progressing, replacing periodic self-reported statements with an escrow that pays only for verified work.
Key Asset Types
Demonstrate provisioning and restoration progress with an auditable trail, recovering committed capital promptly as each milestone is independently verified rather than tied up indefinitely.
Key Asset Types
Attest restoration milestones on-site and give affected communities confidence that closure obligations are funded and being met, with every check sealed in a public progress log.
Key Asset Types
Whether you are bridging a regulator's compliance system or capturing verifier attestations from the field, Cerulea routes both into one milestone-gated closure escrow.

Gated Closure Fund
Building a regulator-visible closure escrow with milestone gating, independent verification, and a sealed progress log from scratch requires specialised engineers and long compliance integration cycles. Calculate your exact deployment speed using Cerulea.

The legacy timeline reflects regulated escrow integration benchmarks. Building custom conditional release logic, wiring independent verifier attestation, and shipping a regulator visibility layer for an average closure fund takes a baseline of 8 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your escrow and milestone rules into pre-audited WebAssembly binaries and provisions the fund and attestation layer instantly.
