3. Choosing—and Maximising—Your Recruiter Partnership

Align by Stack

Solidity devs gravitate toward Plexus or EC1 Partners; Rust/Substrate engineers often use Storm2 or Signify.

Show Proof of Work

Open‑source repos, on‑chain deploys and audit links speak louder than résumés; recruiters pitch those URLs directly to founders.

Expect Coding‑Challenge Prep

Top desks supply sample smart‑contract exercises or CTF‑style exploits. If none are offered, ask.

Negotiate Tokens Wisely

Seek vesting schedules ≥ 2 years with cliff ≤ 6 months; recruiters will benchmark recent deals.

4. In‑Demand Blockchain Skills for 2025 (Explained)

1. Solidity & Hardhat Testing – Security‑first smart‑contract patterns and fuzz testing.

2. Rust/Substrate Development – Building custom parachains or L2s on Polkadot / Cosmos.

3. Zero‑Knowledge Proofs (zk‑SNARKs / zk‑STARKs) – Privacy & scaling solutions in demand.

4. DeFi Risk & Quant Modelling – Python/R skills to model liquidity pools and impermanent loss.

5. DevOps for Web3 – EVM node orchestration, chain‑indexing pipelines and Grafana/Prometheus monitoring.
