Blockchain & Web3 Development Company in Brisbane

Public chain or permissioned network is the fork that decides a Brisbane ledger budget. The shapes are a scoped smart contract MVP at Brisbane rates over six to twelve weeks, covering Solidity or Anchor contracts, a Foundry or Anchor test suite, a deployment runbook, and a written exit plan, a full Web3 product (contracts plus indexer plus wallet UX plus admin console), or an enterprise permissioned ledger for Aurizon-style supply chain or Santos GLNG provenance, including Hyperledger Besu or Fabric setup, validator coordination, and APRA CPS 230 documentation. External smart contract audits with firms like Trail of Bits, OpenZeppelin, or Halborn sit on top at AUD $40,000 to $180,000 depending on contract complexity and custody scope. We give fixed-fee proposals tied to deployment milestones rather than open time and materials estimates.

It depends on token mechanics, not on marketing language. ASIC INFO 225 and the Treasury Digital Asset Platform consultation classify tokens as financial products if they look like derivatives, managed investment schemes, non-cash payment facilities, or pooled investment exposure. Stablecoins, tokenised deposits, yield-bearing tokens, and most fractionalised real-world assets land in scope and require AFSL coverage or a licensed partner. Pure utility tokens, loyalty points, ticketing NFTs, and gameplay items typically sit outside the financial product perimeter but may still trigger AUSTRAC digital currency exchange registration if you facilitate fiat-to-crypto conversion. Our discovery phase produces a written ASIC and AUSTRAC posture memo before any contract is written. Final legal sign-off sits with your AFSL counsel, and we work alongside firms like King and Wood Mallesons, Gilbert and Tobin, or HWL Ebsworth on Brisbane matters.

Yes. We have scoped Australian Carbon Credit Unit (ACCU) and Large-scale Generation Certificate (LGC) tokenisation against the Clean Energy Regulator's ANREU registry specifications, including the Safeguard Mechanism reforms now applying to Santos GLNG, Origin APLNG, Shell QGC, and BHP Mitsubishi Alliance operations. Token designs lock to the underlying registry record, surrender events trigger on-chain burn with regulator-acceptable proofs, and Scope 3 disclosure flows feed straight into the AASB S2 climate-related disclosure narrative. We build MRV (measurement, reporting, verification) pipelines on Hyperledger Besu when counterparty privacy matters, or on Polygon and Base when a public audit trail is acceptable. Stanwell, CleanCo Queensland, and CS Energy renewables counterparties already understand this pattern.

Brisbane financial clients (Suncorp, Bank of Queensland, the Queensland super funds) now scope blockchain custody, settlement, and tokenised asset workloads under APRA CPS 230 from 1 July 2025, which mandates a critical operations register, tested business continuity, severability from material service providers, and tolerance levels for disruption. Our delivery produces a CPS 230 evidence pack including a service provider register entry, BCP documentation with quarterly test scripts, an exit plan that does not assume the launch chain still exists, and tolerance levels measured against on-chain finality (Ethereum 12-second blocks, Arbitrum 250ms confirmations, Solana 400ms slots). CPS 234 information security obligations sit alongside, with key management hardware (HSMs or Fireblocks MPC) and the related access control evidence packaged for internal audit.

The 2032 Brisbane Olympic and Paralympic Games sit in the Codazz Brisbane brief from day one. We have already scoped digital ticketing, sponsor activation, and athlete identity prototypes against the IOC and IPC technical playbook patterns, building on lessons from Paris 2024 ticket fraud and Tokyo 2020 sponsor activation. Production-grade Olympic flows need account abstraction so fans never see gas, throughput on Base, Arbitrum, or Polygon CDK that survives a sponsor moment, geo-fencing aligned with broadcast rights, and accessibility (WCAG 2.2 AA) baked in for IPC compliance. We coordinate AEST sprints with Brisbane Organising Committee timelines, hold an Olympic-class load testing budget aside, and pair every consumer launch with a fraud and AML review against Brisbane CBD and Gold Coast ticket scalping patterns from past international events.

Yes, this is a core Brisbane workload. Aurizon's coal haulage out of the Bowen Basin into the Port of Brisbane, BHP Mitsubishi Alliance metallurgical coal exports, and Santos GLNG and Origin APLNG LNG cargoes off Curtis Island all share a structural problem — multi-party reconciliation across rail, port, surveyor, customs, and counterparty systems is currently spreadsheet and email driven. We build Hyperledger Besu or Fabric permissioned networks with validator nodes hosted by each material counterparty, smart contracts for bill of lading state transitions, and an off-chain attestation layer for ABS, Bureau Veritas, and SGS surveyor data. Privacy is maintained through channel separation (Fabric) or private transactions (Besu Tessera). Outputs feed straight into Scope 3 disclosure under AASB S2.

Ethereum mainnet for tokenised real-world assets where credibility and Lindy effect beat gas cost (Suncorp-scale custody, ACCU tokenisation). Arbitrum and Base for consumer-facing Olympic 2032 fan experiences and Brisbane sport club loyalty, because gas sponsorship via ERC-4337 is mature and bridges to Ethereum mainnet are well audited. Polygon CDK and Polygon PoS for high-volume ticketing where throughput matters more than security budget. Solana for in-venue real-time experiences (Suncorp Stadium, Lang Park, the Gabba) where 400ms slots and Token Extensions matter. Hyperledger Besu or Fabric for permissioned enterprise rails (Aurizon, BHP Mitsubishi Alliance, Santos GLNG) where validator identity is part of the trust model. We avoid recommending chains with thin Australian counsel coverage or unclear ASIC posture.

Every Codazz contract gets Slither, Mythril, and Foundry fuzz tests in CI on each commit, a manual review against the Smart Contract Security Verification Standard (SCSVS) before code freeze, and a written threat model covering reentrancy, oracle manipulation, MEV exposure, and admin key compromise. For any contract touching custody or moving more than AUD $250,000 of value we recommend an external audit with Trail of Bits, OpenZeppelin, Halborn, Sigma Prime, or ChainSecurity, scoped at AUD $40,000 to $180,000 depending on contract size. Post-deployment we wire Tenderly, Forta, and OpenZeppelin Defender alerting into the client's existing SIEM, run a Code4rena or Cantina contest where budget allows, and document a tested pause and migration plan. Our APRA CPS 234 evidence pack maps every control to APRA Prudential Practice Guide CPG 234.
