Mineral Traceability
Mine-to-market provenance for critical minerals, with OECD, Dodd-Frank and EU Battery Regulation requirements embedded directly into smart contracts.
A Verichain × AMSG Protocol
The on-chain backbone for Africa's critical minerals.
Madini anchors every parcel, licence and lot of mineral wealth to a single, tamper-proof ledger — turning OECD, Dodd-Frank and EU Battery Regulation compliance from a cost into infrastructure, and bringing artisanal producers into formal, fairly-priced markets.

The Gap
Real assets move faster than the paperwork that proves who owns them.
Across Africa's mineral economies — from the goldfields of Equatoria to land registries in Juba County — the story repeats: valuable, real-world assets changing hands with no unified, tamper-proof record of who holds title, who verified it, or where it came from.
Opaque origin
Fragmented paper trails make it difficult to verify where a mineral, parcel or licence actually originated, or trace it forward to export.
Duplicate & forged claims
The same lot, parcel or permit can be claimed by several parties at once; forged and back-dated documents pass unnoticed.
No instant verification
A buyer, bank, checkpoint or regulator has no fast way to confirm a title or licence is genuine — enforcement means a trip to the capital.
Value trapped offline
Real assets worth an estimated $16 trillion globally remain illiquid and unbankable, excluding producers from credit and investment.
The Protocol
One notebook. Every party writes to it. Nobody can rewrite the past.
Madini is a Layer-1, EVM-compatible blockchain built for real-world assets. Every authorised party — a surveyor, a cooperative, a registry, a bank — adds a verified entry. Once written, it is locked in place.
-
01
Register
The holder — a miner, land owner or licensee — onboards via mobile, USSD or a local agent. Identity, biometrics and geolocation are captured; no smartphone required.
Output · Verified ID + wallet -
02
Identify
A soulbound, tamper-proof credential is minted on-chain and issued as an NFC/QR smart card — bound permanently to the holder's wallet, never sellable or duplicated.
Output · Smart credential -
03
Verify & Trade
Buyers, banks, courts, exporters and checkpoints confirm authenticity against the chain in real time — and settle trades, royalties and transfers automatically.
Output · Settled, provenanced record
One Protocol, Four Registries
Built to be a single source of truth — whatever the asset.
Gold & RWA Trading
Digital registration and smart ID cards for artisanal miners, feeding assayed lots into a tokenised, real-world-asset marketplace with automatic royalty splits.
Land Title Validation
Geo-tagged, soulbound land titles with a complete on-chain transfer history — ending duplicate claims and giving banks and courts instant verification.
Licence Validation
A single, government-anchored register of who is licensed to mine or trade — scanned and confirmed in seconds by buyers, exporters and checkpoints alike.
Governance
Trust, modelled as a diamond — not a black box.
Madini extends the W3C verifiable-credential model with a governing authority — the state, county or regulator — so every party knows who issued a credential, and that it is genuine.
- Holder
- Miner, land owner or licensee — carries a verifiable credential in a secure wallet.
- Issuer
- The registry or authority — issues the credential, signed and written to Madini.
- Verifier
- Banks, courts, buyers, checkpoints — confirm a credential instantly, with no integration required.
- Governance
- The state or county government — endorses who may issue, underwriting trust in the whole register.
Designed From The Field Upward
Built for the artisanal producer first — everything else follows.
The largest group of users is also the least served by technology. Many work far from offices, may not read or write, and do not own a smartphone. Madini is designed for them first.
No smartphone needed
Register and verify by USSD shortcode on any basic phone — even with no data connection.
An agent, in person
Trusted local agents onboard producers at the cooperative, in their own language.
Biometrics, not paperwork
A fingerprint and a photo are the identity — nothing to fill in, nothing to sign.
A card they can hold
A durable NFC/QR smart card works offline; a single tap proves the credential is real.
Paid directly, fairly
An on-chain wallet settles payment straight to mobile money at transparent prices.
Protected, not policed
Verified status opens legal markets and finance — formalisation that works for the producer.
The Network
One interoperable protocol, endorsed at government level.
Madini is built by Verichain Technologies in partnership with the Africa Minerals Strategy Group (AMSG) — the intergovernmental body behind the Africa Responsible Mineral Sourcing Initiative. Thirty-one member nations have signed the AMSG Charter, adopted at Riyadh and opened for signature at Cape Town, committing to shared standards for traceability, transparency and accountability.
The Republic of South Sudan ratified the Charter in Juba on 17 October 2025 — meaning registries built on Madini already ride on infrastructure the nation has endorsed at the highest level.
Every registration, verification, trade and royalty split is queryable end-to-end — one immutable ledger, read by ministries, regulators, buyers and exporters alike.
Leadership
Governed by people who have built markets, not just protocols.
