Engagement Proposal
Real Estate Token Platform — Blockchain Advisory & Development Partnership
What We Bring to This Project
Regardless of how we engage, your project draws from the same core team and expertise:
Token Architecture
ERC-20, ERC-3643/T-REX, dividend distribution mechanisms
Smart Contract Security
Audit readiness, exploit-resistant design, formal verification patterns
Custody & Key Management
HSM, MPC wallets, transaction signing infrastructure
DeFi Integration
Uniswap, Compound, Aave, on-chain dividend distribution
Regulatory Compliance
Transfer restrictions, investor whitelisting, KYC/AML workflows
Multi-Chain Strategy
Base to Ethereum Mainnet migration and cross-chain architecture
Architecture & Code Review
Layered onto your existing dev cycles for continuous quality assurance
Service Line 1: Advisory
Advisory gives you on-demand access to senior blockchain architects who guide your technical decisions, review designs, and keep your build aligned with security and compliance best practices — without embedding full-time engineers.
Advisory Essentials
Best suited for early architecture and design phases
- Bi-weekly strategy calls (60 min)
- Async access via Slack/email between calls
- Monthly written architecture brief
- Document and design reviews
- ERC-3643 tokenization guidance
- Priority security incident response
Advisory Pro
Best suited for active build phases
Everything in Essentials, plus:
- Weekly strategy calls (60 min)
- 4-hour async SLA (business hours)
- Pull request and code reviews
- Custody architecture deep-dive sessions
- ERC-3643 compliance audit preparation
- Monthly DeFi ecosystem briefing
- CTO-level access for ad-hoc escalations
Service Line 2: Team Extension
Embedded engineers join your daily standups, work inside your repositories, and ship production code as part of your team. They bring deep blockchain and full-stack expertise without the overhead of full-time hiring.
What embedded engineers work on:
- Smart contract development (ERC-20, ERC-3643, dividend logic)
- Backend services — APIs, indexing, wallet infrastructure
- Frontend integration — token dashboards, investor portals
- Testing and audit preparation — unit tests, fuzzing, formal verification
- DevOps and deployment — CI/CD, multi-chain deployment pipelines
- Documentation and knowledge transfer to your internal team
Daily Rates
| Commitment | Daily Rate |
|---|---|
| Short-term / Flexible | $1,000/day |
| 3-month | $950/day |
| 6-month | $900/day |
| 12-month | $800/day |
Team scaling is flexible. Start with one engineer and add capacity as requirements mature. All engineers are senior-level with a minimum of 4 years of blockchain-specific experience.
Illustrative Monthly Investment
At 12-month rate · ~21.5 working days/month
| Team Size | Monthly Estimate |
|---|---|
| 1 senior engineer | ~$17,000 |

Combining Both Service Lines
Most clients start with Advisory to lock in the architecture, then layer in embedded engineers once the blueprint is clear. Here is a typical ramp:
Advisory Pro — $5,000/mo
Architecture design, compliance mapping, custody blueprint, ERC-3643 token model
Add 1 embedded senior engineer
Begin smart contract implementation at short-term rate ($1,000/day) while Advisory Pro continues
Convert to long-term commitment
Move to 6 or 12-month rate, keep Advisory Pro running for ongoing architectural oversight
This approach reduces early-stage risk by validating architecture and compliance requirements before committing to full-scale development resources. You only pay for engineering capacity when the foundation is proven.
Why Webisoft
Our team has shipped production blockchain systems across EVM, Solana, Terra, Cardano, and Midnight. We have navigated real exploits, not just theoretical ones — from flash loan attacks to bridge vulnerabilities — and bring that incident-response muscle to every engagement.
Multi-Chain Depth
Production deployments across EVM chains, Solana, Cardano, and Midnight. We choose the right chain for the job.
Real Incident Experience
Hands-on response to exploits, not just audits. We have seen how contracts fail in the wild.
Full-Stack Context
We build frontends, backends, and smart contracts — so nothing falls between the cracks at integration points.
Flex Engagement Model
Scale up or down month to month. No long lock-ins, no bench time billed to you.
