Engagement Proposal

Real Estate Token Platform — Blockchain Advisory & Development Partnership

Jason Urton·Webisoft·March 31, 2026·v1.0
Section 01

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

Section 02

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

$2,500/mo
  • 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

Recommended

Best suited for active build phases

$5,000/mo

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
Section 03

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

CommitmentDaily 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.

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:

1
Months 1-2

Advisory Pro — $5,000/mo

Architecture design, compliance mapping, custody blueprint, ERC-3643 token model

2
Month 3

Add 1 embedded senior engineer

Begin smart contract implementation at short-term rate ($1,000/day) while Advisory Pro continues

3
Month 4+

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.
