Securely manage wallets and seed phrases; compare hot, cold, custodial, multisig and smart-contract wallets; apply protection practices.
Compose and sign transactions correctly, addresses, value, fees/gas, signatures, nonces, and metadata, across major chains.
Optimise fees and navigate multi-chain UX, reduce costs, use L2s, and move safely via bridges with clear risk controls.
Program Overview
This hands-on program shows exactly how crypto transactions work in the real world. We start with wallet security, private keys, seed phrases, and the trade-offs between hot, cold, custodial, and non-custodial setups. Then we unpack transaction composition step-by-step using the Anatomy of a Transaction diagram (addresses, value, fee/gas, signature, nonce, metadata). Finally, we demystify network fees with practical tactics to cut costs and explore interoperability, multi-chain wallets and bridges, including why bridge mistakes/hacks cause irreversible loss. Learners finish with the confidence to transact, troubleshoot, and teach others safely.

Skills Gained & Business Application
You’ll turn crypto from “mystery clicks” into repeatable, auditable workflows. Master wallet setup and recovery hygiene, implement hardware, multisig, and smart-contract wallet guardrails, and spot scams before they bite. Build and verify transactions end-to-end, checking nonces, parsing metadata, and right-sizing gas, while reducing costs with Layer 2s, batching, and off-peak strategies. You’ll also design multi-chain journeys that don’t strand funds: choose safer bridges, prevent address-format mistakes, and set policies for revoking approvals and segregating wallets (test/trade/treasury). The payoff is immediate: fewer incidents, faster onboarding, lower fees, and clearer guidance for clients and colleagues.
Who this program is ideal for
✓ Ops, security & custody teams: Enforce key-management, multisig policies, hardware-wallet standards, and approval-revocation routines. ✓ Product managers & solution architects: Design low-friction transaction flows, fee-optimised paths, and safer cross-chain UX. ✓ Risk, compliance & legal: Define wallet tiers, segregation, and bridge risk controls; document irreversible-transaction and disclosure procedures. ✓ Client services, treasury & finance ops: Execute transfers with fewer errors, pick fee strategies, and standardise audits/receipts for stakeholders. ✓ Engineers & QA: Validate transaction fields (signature/nonce/ABI data), implement gas-efficiency and L2 pathways, and instrument approval monitoring.
